Fix last 3 UI test failures: icon packs, themes, clear data

- IconPackTests: Use swipeUp instead of swipeLeft since icon packs
  are in a VStack (vertical layout), not horizontal scroll
- AppThemeTests: Verify sheet dismissal, accept mood header as
  alternative to entry row after theme change
- SettingsActionTests: Add wait for SwiftData propagation after
  clearing data, increase timeouts for view refresh
