refactor(message): improve message synchronization and hook reliability

Refactor the message management system to address synchronization issues and improve performance through request deduplication and enhanced lifecycle management.

- Implement in-flight promise tracking in `MessageSyncService` to prevent redundant network requests for conversations and messages.
- Enhance `useMessages` hook with `useFocusEffect` to trigger automatic synchronization when a chat screen regains focus.
- Add `forceSync` capability to `MessageManager` and `MessageSyncService` to allow manual overrides of loading states during re-entry.
- Consolidate WebSocket synchronization logic in `WSMessageHandler` using a throttled and deduplicated trigger mechanism.
- Clean up unused styles and deprecated hooks (`baseHooks.ts`, `bubbleStyles.ts`, `inputStyles.ts`).
- Update `metro.config.js` and `package.json` to include `@expo/ui` and optimize resolver settings.
