feat: integrate UserPreferencesContext for improved preference management

- Added `UserPreferencesProvider` to `RootLayout` for centralized user preferences handling.
- Updated components to remove direct user preferences fetching, relying on context instead.
- Enhanced SSR data fetching by consolidating user preferences retrieval into a single service call.
- Cleaned up unused props in various components to streamline the codebase.
