refactor: remove offline indicator and streamline chat page logic

- Deleted the OfflineIndicator widget and its associated logic to simplify the codebase.
- Removed offline checks from the ChatPage, enhancing performance and reducing unnecessary rebuilds.
- Adjusted the ChatsDrawer to change icon size for better visual consistency.
- Cleaned up unused imports related to offline handling across multiple files.
