refactor: enhance search field styling in ChatsDrawer

- Wrapped the TextField in a Material widget to improve styling and ensure proper background handling.
- Added TextDecoration.none to various text styles to remove underlines, enhancing visual consistency.
- Updated the search field's input decoration for better alignment with the app's theme and design standards.
