artcraft-native: generate with Midjourney or fal (provider choice) (#2115)

Images can run on Midjourney (own account, via a sign-in window) or fal (own API key), chosen from the model selector's Select Provider submenu. Jobs finish into the library. The Midjourney credential manager and the router prompt helper move into shared crates used by both desktop apps.
