Fix widget issues and add subscription bypass toggle

Widget fixes:
- Fix App Group ID mismatch in iOS app entitlements (was group.com.tt.ifeel.ifeelDebug, now group.com.tt.ifeelDebug)
- Fix date bug where missing entries all showed same date
- Add sample data preview for widget picker (shows realistic mood data)
- Add widgetDisplayName to Mood enum for widget localization
- Update Mood Vote widget preview to show post-vote state
- Attempt to fix interactive widget buttons (openAppWhenRun: false)

Developer improvements:
- Add IAPManager.bypassSubscription toggle for testing without subscription
