CLI commands failed with "unable to open database file" because
environment variables weren't loaded from .env before create_app().
Now checks multiple .env locations:
- Same directory as cli.py
- Parent directory
- /opt/serverkit/.env (production)
- /opt/serverkit/backend/.env
Add --debug flag to show which env file was loaded.

Introduces a comprehensive Bash CLI tool (`serverkit`) for managing ServerKit services, users, and database operations. Adds a quick-install script (`install.sh`) for Ubuntu, a sample environment file (`.env.example`), and a Python CLI backend (`backend/cli.py`) for administrative tasks. Updates Docker Compose for production readiness, enhances deployment documentation, and adds Click to backend requirements. Also updates references to the correct GitHub repository.
