test(ai): expand AI flow and clipboard semantic coverage

- Cover reply-variant decision paths, scene-detector abstention, and
  the merged reply center stance catalog.
- Lock in clipboard semantic analyzer thresholds, complaint-only
  suppression, and existing-skill routing.
- Add durable session, refresh, and managed-gateway reliability tests
  for the Apple account path.
- Verify personal-style prompt derivation, low-confidence ASR
  tendencies, and Polish style learning against real corpus evidence.
- Exercise the assistant keyboard and Polish styles UI flows in
  end-to-end UI tests.
