Fix remaining 17 UI test failures: group defaults, identifiers, hittability, date format

- resetAppState: use correct suite name to clear group defaults (fixes stale subscription state)
- Reorder configureIfNeeded: set expireTrial before IAPManager init
- Add browse_themes_button identifier to CustomizeView Browse Themes button
- Add mood_button_* identifiers to Entry Detail mood grid in NoteEditorView
- Use coordinate-based tap throughout all test screens (iOS 26 Liquid Glass hittability)
- Fix HeaderMoodLogging date format: M/d/yyyy → yyyy/MM/dd to match entry_row identifiers
- AppLaunchTests: wait for isSelected state with NSPredicate instead of immediate check
- OnboardingTests: add waits between swipes and retry logic for skip button
