web-app-chess: refactor runtime & entrypoint

- Move entrypoint to files/ and deploy via copy
- Parameterize APP_KEY_FILE, data dir, and entrypoint paths
- Require explicit PORT/PG envs (remove fallbacks)
- Drop stray header from config/main.yml
- Dockerfile: use templated data dir & entrypoint; keep node user
- Compose: set custom image, adjust volume mapping
- env: derive APP_SCHEME from WEB_PROTOCOL; NODE_ENV from ENVIRONMENT
- tasks: add 01_core and simplify main to include it
