Fix 23 failing UI tests: accessibility hierarchy, test mode, and interaction issues

App fixes:
- Remove empty_state identifier from EmptyHomeView VStack (was overriding mood_header)
- Fix resetAppState to set needsOnboarding=true (fresh state) instead of false
- Set bypassSubscription explicitly based on launch arg presence (was defaulting to true in DEBUG)

Test fixes:
- TabBarScreen: use coordinate tap to avoid iOS 26 Liquid Glass hittability issues
- SettingsScreen: use coordinate tap for segments, handle Settings label ambiguity with tab bar
- EntryDetailScreen: use mood_button_ identifiers instead of label matching (was matching entry rows)
