fix(watch): kick sync service unconditionally on app start

Without this, the watch would only run a poll cycle if the pending
queue happened to be non-empty — meaning the case list was empty
forever for users who didn't dictate before opening the app. Kicking
on every launch makes the foreground service start, primes the case
store from the snapshot cache, then polls /api/oneliners.

Verified end-to-end on Wear OS 36 emulator-5556 against a live local
server:
- 4 server cases populate the list within ~150 ms of app start
- Tap Neu → mic permission → record → stop completes in <3 s of UI
- Sync service uploads, server transcribes (whisper) + classifies
  (ollama), watch's burst-poll hits within 2 s of upload-success and
  merges the OnelinerState.Empty (silence rule) back into the marker
- unsynced/ ends empty (deletePair after ACK), cases/ has 5 markers
  with synced_to_server=true, snapshot_cache.json on disk
