chore: run CI on PRs, require POSTGRES_PASSWORD, document HTTPS need

- .gitea/workflows/deploy.yml: trigger on pull_request to main so PRs
  get test feedback; gate build-and-push + deploy on push events so
  PRs only run the test jobs (no registry push, no SSH deploy).
- docker-compose.yml: change `${POSTGRES_PASSWORD:-mangalord}` to
  `${POSTGRES_PASSWORD:?...}` so a deploy without an .env fails fast
  instead of booting Postgres with a known-default credential.
- .env.example: change the example value to a "change-me" sentinel,
  add a banner explaining that production needs HTTPS in front of
  the frontend container because COOKIE_SECURE=true makes browsers
  refuse cookies over plain HTTP.
