Enhance bot functionality and refactor database interactions

- Added `ca-certificates` installation to Dockerfile for improved network security.
- Updated health check command in Dockerfile to include better timeout handling.
- Refactored `run_helper.py` to implement proper signal handling and logging during shutdown.
- Transitioned database operations to an asynchronous model in `async_db.py`, improving performance and responsiveness.
- Updated database schema to support new foreign key relationships and optimized indexing for better query performance.
- Enhanced various bot handlers to utilize async database methods, improving overall efficiency and user experience.
- Removed obsolete database and fix scripts to streamline the project structure.
