Refactor code to utilize aiofiles for asynchronous file handling across multiple modules. Added a new function to remove blocked users from the database and updated user blocking/unblocking logic to use this new function. Improved database interaction in admin panel handlers by passing session objects instead of creating new connections. This enhances performance and maintains consistency in file operations.
