Update banned users handling with async support and improved date parsing

- Modified `change_page` function in `callback_handlers.py` to use async methods for retrieving banned users and their buttons.
- Enhanced `get_banned_users_list` in `helper_func.py` to handle string timestamps and various date formats, ensuring robust date parsing.
- Added a new test case in `test_utils.py` to validate the handling of string timestamps in the banned users list retrieval.
