- add guard clause to prevent duplicate clicks when posting is in progress
- replace navigation.goBack() with navigation.reset to Main screen for cleaner navigation stack after post creation, update, and voting post submission
Replace direct `navigation.navigate()` and `navigation.getParent()?.navigate()` calls with centralized `navigationService.navigate()` across multiple screens. Convert screen component functions from JSX elements to array-returning functions in RootNavigator to fix React key warnings and improve render consistency.
- HomeScreen: use navigationService for post and user navigation
- PrivateChatInfoScreen: use navigationService for profile navigation
- ChatScreen: use navigationService for avatar press and user profile navigation
- RootNavigator: convert PublicScreens and AuthenticatedScreens to getPublicScreens() and getAuthenticatedScreens() functions returning arrays with proper keys
- add educational system synchronization with username/password authentication
- implement long-press course deletion with single/all options
- add multi-lane course display for overlapping same-name courses
- refactor course detail screen with ScrollView and improved layout
- fix teacher display to show per-time-slot instructors instead of single field
- add settings modal with sync option and loading states
Add new ScheduleTab to main navigation with ScheduleStackNavigator for managing course schedule screens. Includes CourseDetailScreen with modal presentation. Also exports scheduleService and related types for the new schedule feature.
fix(message): add group_id parameter to invite and request handlers
Pass group_id from extra_data when calling respondInvite and reviewJoinRequest APIs, as the backend now requires this parameter.
refactor(message): extract mergeMessagesById helper method
Centralize message merging logic into a reusable private method to avoid duplication and ensure consistent message deduplication behavior.
