fix codegen + also codegen query cache

Removes Font Awesome entirely

### Changes

- All ~1,000 icon call sites now import Lucide components directly from
`lucide-react` (`<PlayIcon className="..." />`); no FA packages, tokens,
or `fa*` identifiers remain anywhere.
- New `@storyteller/icons` lib holds the pieces Lucide doesn't ship:
`DynamicIcon` for runtime-chosen icons (`icon={loading ?
LoaderCircleIcon : SaveIcon}`), 11 brand logos (Discord, TikTok, ...) as
inlined CC BY 4.0 paths, and HD/SD quality badges drawn in Lucide's
stroke style.
- Global `.lucide { display: inline-block; width/height: 1.2em }` rule
in each app stylesheet: keeps icons font-relative like FA (1.2em
compensates Lucide's 24px-viewBox/20px-grid padding) and undoes Tailwind
preflight's `svg { display: block }`. Explicit `w-*`/`size-*` utilities
still win.
- FA-only props migrated: `spin` → `animate-spin`, FA size strings → em
values.
- Dropped `@fortawesome/*` + `@awesome.me` kit deps, both `.npmrc`
files, and
the FA rule in `shared-vite-config.ts` (now externalizes
`lucide-react`).

 # Testing
 
+## Database Fixture Tests
+
+- Live in-crate (e.g. `storyteller-web`'s omni_gen video pricing tests) and
+  use the `mysql_testing` crate (`crates/schema/database/mysql_testing`) for
+  guarded pools, schema setup, and account/session/wallet fixtures
+- They RUN BY DEFAULT with `cargo test -p storyteller-web` and from the IDE
+  (requires a local MySQL with an `artcraft_test` database). Machines/CI
+  without MySQL skip them via the off switch:
+  `SQLX_OFFLINE=true cargo test -p storyteller-web --features skip_database_tests`
+- They connect ONLY via `ARTCRAFT_TEST_DATABASE_URL` (default
+  `mysql://root:@localhost:3306/artcraft_test`); the guard panics on any
+  database whose name lacks "test", on `storyteller`/`artcraft`, and on
+  cloud hosts — see `mysql_testing/README.md`
+- Database tests run in PARALLEL: each test creates its own users, wallets,
+  and rows; schema setup single-flights via a MySQL named lock. Only tests
+  mutating shared/global state take
+  `mysql_testing::serial::acquire_serial_test_lock().await`
+- External providers must never be called: the harness stubs Kinovi with an
+  in-process HTTP server via `KINOVI_CUSTOM_API_HOST`/`KINOVI_CUSTOM_CDN_HOST`
+
 ## Running Tests
 
 - Most crates: `cargo test -p {crate_name}`

+# PageScene Animations — Branch Handoff
+
+Branch: `frontend/pagescene-animations` (forked from `main` @ `6329045350`, 2026-08-04).
+Everything below is TypeScript-typechecked per-lib (`tsc -p <lib>/tsconfig.lib.json`); runtime
+verification status is tracked in the checklist at the bottom. Drag-and-drop has had one manual
+pass (confirmed working); most other surfaces have not been launched.
+
+## What this branch does
+
+Makes skeletal animations a first-class asset in the 3D editor (pagescene): browse them in the
+asset drawer, drag them onto characters or the timeline with live rig-compatibility feedback,
+play clips baked into uploaded models, preview animations everywhere models are previewed, and
+upload Mixamo FBX files (with or without mesh) end to end.

+## Features
+
+### 1. Animations tab in the asset drawer (`AssetModal`)
+
+- New left-rail section fed by `GET /v1/media_files/list_featured?filter_engine_categories=animation`
+  (GLB/GLTF only — the clip loader is GLTF-based). Featured results REPLACE the 37 hardcoded
+  `demoAnimationItems`; demos are only the empty-API fallback.
+- The session user's own uploaded animations (`list/user`, same filter) render AHEAD of the
+  featured set. Fetched on every modal open and after each upload; fails silently for anonymous
+  users (`suppressErrorToast` on the user-media fetch path).
+- Card click appends the clip to the selected character's row at the earliest free slot (toast
+  when no character is selected or the row is full). The old right-docked `AnimationsDrawer` is
+  deleted; the old HTML5-DnD path (`ANIMATION_CLIP_MIME`) is gone with it.
+
+### 2. Drag-and-drop with rig-compatibility badge (`DndAsset`)
+
+- Animation cards ride the same pointer-drag pipeline as every other asset. On drag start the
+  clip's track node names are preloaded (`loadRawGlb`, cached per media id); hovering a
+  character (or any skinned object) checks those names against its nodes — the exact direct-bind
+  rule `CharacterAnimationManager` plays by. No retargeting (explicitly out of scope).
+- The shared `DragGhost` shows the verdict: green check (binds) / red slash (no target or rig
+  mismatch); nothing while the clip is still loading. Incompatible or slot-less drops are
+  rejected with a toast.
+- Drop targets: a character in the 3D scene (earliest free slot) or a timeline row
+  (`data-clip-drop-uuid`; pointer-x → time via the `data-timeline-ruler` rect).
+
+### 3. Timeline clips: behavior + UX
+
+- **Strips default to 1 s** and the strip width is the authoritative play window
+  (`LaneRuntime.stripDuration`): trimming genuinely cuts playback; loop repeats inside the
+  strip; a non-loop strip wider than its clip freezes on the last frame. On load a strip only
+  shrinks (clip shorter than default) — never grows.
+- **Rest-pose in gaps**: `Skeleton.pose()` was replaced with a rest-pose snapshot captured at
+  mixer creation (all nodes BELOW the object root; root excluded so gizmo/keyframes never snap
+  back). `pose()` rebuilds bone locals from inverse bind matrices and mis-scales cm-rigs — that
+  was the "character vanishes when moving a strip" bug.
+- **Selection UX**: strips are click-to-select; × renders only on the selected strip;
+  Del/Backspace deletes; removal is individually undoable (`RemoveClipLaneAction` — the one
+  exception to clip edits riding the timeline Save/Cancel session).
+- **Full rows reject adds**: `resolveFreeStart` returns null instead of accepting an
+  overlapping clamp.
+
+### 4. Baked-in clips
+
+- `ClipStrip.bakedClipIndex` marks a strip sourced from the object's own `animations[]`
+  (resolved synchronously — no media fetch). Objects with baked clips get a timeline clip row
+  with a "+" picker listing them.
+- Clip-row eligibility is wider than characters: any skinned object (creatures, rigged uploads)
+  accepts animation drags (bind check gates); baked-only objects get a row for the picker.
+- INVARIANT: baked clips are never removed from the THREE model. Removing a baked strip only
+  unschedules it; the clip stays on `object.animations` and in the picker. Library strips stay
+  fully removable.
+- Outliner metadata (`hasSkeleton`, `bakedClips`) is computed in `convert_object` and refreshed
+  after every GLB load (`SceneDeps.onGlbLoaded` → `refreshOutliner`).
+
+### 5. Previewers (Viewer3D + upload preview)
+
+- Both play baked clips: autoplay the first, dropdown with every clip + "T-pose (none)", hidden
+  entirely for animation-less models.
+- Both have a bone icon toggling a skeleton overlay — default ON when the model has no mesh
+  (Mixamo "without skin" exports), so animation-only files are visible. The upload thumbnail
+  snapshot then captures the skeleton render.
+- The overlay adapts to the rig kind: real `THREE.Bone` joints get `THREE.SkeletonHelper`;
+  mesh-less models whose joints re-imported as plain nodes get `NodeHierarchyHelper`
+  (exported from `viewer-3d`) — GLTF only round-trips bone-ness through a *skin*, and a
+  mesh-less export has no skin, so converted FBX animations lose `Bone`-ness entirely. The
+  toggle shows for `hasBones || !hasMesh`.
+- Latent bugs fixed: upload preview discarded `gltf.animations`; its child re-parenting loop
+  skipped every other child (`scene.add` mutates the array mid-forEach); its mixer bound before
+  the model entered the scene (silently played nothing); camera framing NaN'd on empty
+  bounding boxes (now falls back to bone world positions); camera now fits once, not per-child.
+
+### 6. FBX upload support
+
+- The 3D uploader accepts `.fbx` and normalizes it at the door: `FBXLoader` → `GLTFExporter`
+  → binary GLB with clips preserved. Runs in a dedicated Web Worker (transferred buffers, jobs
+  naturally serialized); a broken worker environment falls back to the main thread. The raw FBX
+  can never reach the backend — retry of a failed conversion re-converts.
+- Caveats: embedded textures may not survive; units are exported as parsed (cm-scaled Mixamo
+  rigs are not rescaled).
+
+### 7. Upload as Animation
+
+- Mutually exclusive checkbox next to "Upload as Character" → `engine_category=animation`.
+  Mesh-less files preselect it (preview loader reports `hasMesh:false`); a user click always
+  wins. Rig-type dropdown defaults to Mixamo (characters keep Mixamo ArKit first).
+- The backend-required `maybe_duration_millis` is read from the longest clip at submit time;
+  clip-less files are flagged and excluded client-side.
+
+### 8. Outliner skeleton toggle (`SkeletonHelperController`)
+
+- Bone icon on skinned rows toggles a persistent `SkeletonHelper` on LAYER 1 (editor-only —
+  the render camera renders layer 0, so skeletons never appear in captures/recordings).
+- Persists as `userData.skeletonVisible` through scene save/load (explicit restore in the proxy
+  load path). Reconciliation rides `OutlinerRefreshedEvent` — add/delete/load/new-scene and the
+  post-GLB-load refresh all funnel there.
+- FK/pose-mode compatible: `PoseModeChangedEvent("pose")` suppresses the persistent helper for
+  the posed character (FKHelper draws its own rig); exit restores it. The toggle state itself
+  is never touched.
+
+## Manual test checklist (outstanding)
+
+- [ ] Prod data: does `list_featured?filter_engine_categories=animation` return rows? If yes
+      they replace the demo clips in the tab; if empty, the 37 demos show.
+- [ ] Clip→rig bind smoke test on shipped characters (runtime-unverified `mixamorig:*`
+      assumption; a "bound 0 tracks" console warning means retargeting becomes the real task).
+- [ ] Creature experiment: drag a clip onto a creature — badge should reflect bind result.
+- [ ] Baked clips: "+" picker on an animated object's row; add/remove/re-add; save/reload
+      persistence (the `object.animations` stash on load is gated on `auto_add` — statically
+      unconfirmed for every load path).
+- [ ] Clip UX round: strips at 1 s; trim semantics; select → ×/Del; undo/redo of removal;
+      character stays visible when a strip moves off the playhead.
+- [ ] FBX round trip: pick `.fbx` → converts (worker; check console for worker load failures —
+      falls back to main thread) → skeleton visible + clip dropdown → Upload as Animation
+      preselected → appears at front of Animations tab → drag onto character → plays.
+- [ ] Converted-FBX scale: if placed objects come in ~100× too big, the converter needs a
+      normalize-scale step.
+- [ ] Outliner bone toggle: on/off, FK-mode enter/exit restore, save/reload persistence, and
+      absence from Capture/Record output.
+- [ ] Previewer dropdown + bone toggle across lightbox, media page, lightbox-modal,
+      ImageTo3DExperience, upload modal.
+
+## Debug pass + hardening round (post-review)
+
+A four-agent review of the combined branch produced 30 findings (5 high / 12 medium / 13 low);
+ALL have been fixed or explicitly closed, one commit per finding (range `72cb218e..b21732d1`).
+Highlights, roughly in commit order:
+
+- Highs: baked clips cloned per lane (shared-AnimationAction playback/removal corruption);
+  runtime revalidation for objects recreated under the same uuid (delete→undo, reloads) — later
+  hardened into LOOP-FREE terminal lane states (bound / missing / unbindable, reassessed only on
+  root-instance change; the pre-fetch rig gate is sound because every load path stamps the target
+  uuid only post-load); skeleton-helper sync self-heals across in-session reloads; upload modal
+  can no longer report success for empty/partial submissions; ref-guarded double-submit.
+- Mediums: strip removal mirrored into the Save/Cancel `saved` snapshot (Cancel can't resurrect,
+  no phantom undo); stale strip/keyframe selections pruned in the bridge + live-checked before
+  swallowing Del/Backspace; one winning lane per character at flush boundaries (blend-glitch
+  frame was being ENCODED into recordings); orphaned tracks/lanes filtered from scene JSON at
+  save; per-clip queued-drop tokens; animation raycasts gated to the canvas element + honest
+  front-most-surface occlusion; virtualized-grid thumbnail state keyed by item; one shared
+  lazily-fetched animation-library store (was double-fetch + double-toast + divergent lists);
+  previewer rest-pose snapshots replace `Skeleton.pose()` everywhere; all-node camera-framing
+  fallback for plain-node rigs; upload-preview races (superseded-load cancellation, snapshot
+  after helper creation, File-identity row statuses, retry re-entry).
+- Lows: duration-shrink re-fits strips; baked-clip picker portals out of the scrolling row list;
+  timeline resets on scene switch/new scene instead of leaking across; click-to-add accepts every
+  drag-eligible target; queued drops bail on a torn-down editor (`Editor.isLive`); top-level root
+  lookups unified; flick-click race killed via `wasDragGesture`; converting-overlay control reset;
+  conversion completions reload only the previewed entry; worker `onmessageerror` recovery +
+  corrupt-vs-clip-less error messages + explicit `initialCategory` wins over mesh-less
+  auto-detect; Uploaded tab pages past the 100-item cap.
+- Closed without code: the "compat cache stales on streaming characters" finding (invalidated —
+  uuid-resolvable roots are always fully loaded) and the Tauri `promptSignup` gap (desktop is
+  always signed in by adapter contract).
+
+## Landed since the original handoff
+
+- **AnimationsModal** (was deferred — now built, `5f7ba7bbc5`/`79875d8c76`): standalone modal
+  with All / Presets / Uploaded tabs, opened from an "Add Animation" button next to Enter Pose
+  Mode and from the "+" add-asset menu. Adding a clip expands the timeline and scrolls to the
+  character (`timelineRevealObjectUuid`); the modal closes after an add unless "Reopen after
+  adding" is on. Its "Upload animation" button opens `UploadModal3D` with
+  `initialCategory="animation"` (anonymous users get the signup prompt), landing on the
+  Uploaded tab afterwards. `AssetModal`'s animations tab was folded into this.
+- **Timeline QoL**: ruler tick marks (major/second/sub-tick), selected-object-only track
+  filter, directional expand/collapse chevrons, thumbnail-less animation cards get an icon
+  placeholder.
+
+## Deferred (explicitly out of scope for this branch)
+
+- **Split-screen preview window** (based on the `?output=` `DemoOutputOverlay`) — parked until
+  explicit approval.
+- **Retargeting** (`SkeletonUtils.retargetClip`) — too complex for now; mismatched rigs are
+  simply rejected by the bind check.
+- **Clip blending/layering** — one non-overlapping row per object, by design.
