refactor(ios): migrate NavigationLink to value-based routing, add Dynamic Type support, fix gesture conflicts

- Replace all deprecated NavigationLink(destination:) with NavigationLink(value: Route)
- Add Route enum with navigationDestination mapping in new Core/Navigation/
- Extract 7 new sub-page files (AIChatPage, AIFeedbackPageView, RecallTestPage, WeakPointsPage, FeedbackFormView, GoalSettingDetailView, MethodPreferenceView)
- Add @ScaledMetric-based zxFontScaled modifier for Dynamic Type
- Fix ZXPressModifier gesture conflict with ScrollView using onLongPressGesture
- Enlarge touch targets from 36pt to 44pt
- Add accessibility labels to TextField and other controls
