Biometric:
- Handle onAuthenticationError with auto-retry (except user cancel)
- Show lock screen with proper UI and an Unlock button as fallback
- Add subtitle clarifying fingerprint/PIN options
Sync engine:
- Fix data race: async coroutines now return FileOutcome instead of
mutating shared vars/list concurrently (was causing file states to
not be saved, so every sync re-transferred all files)
- Fix remoteChanged: use || instead of && so either etag or
modifiedAt change is enough to detect a remote modification
