feat: add user preferences for online status and read receipts with real-time updates

- Introduced `showOnlineStatus` and `showReadReceipts` fields in the user schema and API.
- Integrated real-time status broadcasting in `UsersService` via `EventsGateway`.
- Updated repository and frontend user types to align with new fields.
- Enhanced user update handling to support dynamic preference changes for online status.
