refactor(database): migrate to new modular database layer and unify data access
- Remove legacy database.ts, LocalDataSource.ts, and MessageRepository.ts - Create new src/database/ module with messageRepository, userCacheRepository, conversationRepository, and groupCacheRepository - Update all consumers to import from @/database instead of services/database - Add web platform blur handling for modal components to fix focus issues - Flatten SystemMessageItem and NotificationsScreen styles for consistent design - Add draggable slider in ChatSettingsScreen and dynamic font size support - Introduce 9 new chat color themes - Add profile screens for about, terms, and privacy policy with navigation routes - Add policy links to login and registration screens - Fix post share URL format from /posts/ to /post/
