feat(Dependencies): add new libraries for enhanced functionality and update existing ones

- Added `katex`, `markdown-it`, and `prismjs` for improved rendering of mathematical expressions and markdown content.
- Included `react-native-webview` to support web content within the app.
- Updated package versions in `package-lock.json` and `package.json` for better compatibility and performance.
- Refactored notification handling in `sseService` and `systemNotificationService` to improve user experience with vibration feedback.
- Introduced buffering for SSE messages in `messageManager` to prevent race conditions during initialization.
