Subject: [PATCH] Add CLI flags for port, host, and database configuration

- Added --port flag to override SERVER_PORT
- Added --host flag to override SERVER_HOST
- Added --db flag to override DB_DRIVER
- Added --db-name flag to override DB_NAME

CLI flags take precedence over environment variables for easier
deployment without Docker.
