- Update `main.dart` dependency injection: - Create `ApiClient` and pass it to repositories. - Remove `FirestoreService` injection (or keep only if still used for something else, but ideally remove). - Remove unused Firebase client packages only if safe (later step): - Keep Firebase Auth if you use it to obtain ID tokens. - Remove Firestore client SDK only after all references are gone. - Deliverables: - App compiles cleanly. - No repository directly imports Firestore/Storage.
