fix: Remove fake HAPPY_CODER_API_KEY, use actual Happy Coder env vars

Happy Coder does not require an API key. It uses these environment variables:
- HAPPY_SERVER_URL (optional custom server)
- HAPPY_WEBAPP_URL (optional custom webapp)
- HAPPY_HOME_DIR (data directory)
- HAPPY_EXPERIMENTAL (enable experimental features)

Changes:
- Remove HAPPY_CODER_API_KEY from all files
- Add proper Happy Coder environment variables to StatefulSet
- Add Happy Coder config options to ConfigMap
- Update README with correct Happy Coder configuration
- Update Makefile and docker-compose examples
- Update secrets-example.yaml
