1.0.5: Eating out slots, rule violations panel, Crashlytics, search bar fix

- Eating out: tap any empty slot → "Mark as eating out"; shows teal indicator,
  skipped by auto-assign, counts as complete, tap again to unmark
- Rule violations panel: access via wand long-press context menu when conflicts exist;
  shows all isRuleOverridden slots with Fix (clear) or Ignore (acknowledge) actions
- Firebase Crashlytics integrated: CrashlyticsService + dSYM upload build phase,
  isPremium property tracked per session
- PremiumSyncService: extracted premium state machine, StoreKit Transaction.updates
  listener, isPremium no longer synced via iCloud to avoid stale state
- StoreManager: analytics on purchase/restore, bundle ID fallback for product ID lookup
- Search bar contrast bug fixed: TextField now has explicit foreground color for dark mode
- WelcomeStepView: redesigned onboarding welcome screen with week preview
- Version bump: 1.0.5 build 22
