1.2.0: contextual notifications + in-onboarding auto-fill (aha moment)

- New "Week Ready" onboarding step: auto-fills the first week inline right
  after dish creation, then pitches the Sunday reminder with context before
  requesting OS notification permission (no more cold prompt on Home)
- Notifications section in Settings: weekly reminder toggle, deep-link to
  system settings when permission is denied
- NotificationService: remindersEnabled preference, requestPermission(),
  authorizationStatus(), cancelAllReminders()
- Post-onboarding premium prompt deferred to 2nd session (paywall was just
  shown as the final onboarding step — 2s-later alert was prompt fatigue)
- Back navigation blocked after onboarding commit to avoid duplicate dishes
- 10 new strings × 6 languages
