feat(db): enhance database configuration with environment variable support

- Introduced a function to read database credentials from a file for improved security.
- Added support for environment variables to configure database connection, replacing hardcoded values.
- Implemented a warning for users relying on deprecated hardcoded credentials, encouraging migration to Docker Secrets.
