chore(komodo): switch to image-based deploys, trim CI pipeline

- docker-compose.yml: replace build: sections with image: refs
  (git.buzzbee.dev/BuzzbeeSCD/projecte-{svc}:)
- ci.yml: remove deploy + smoke jobs (Komodo owns build+deploy)
- DEPLOY.md: rewrite for Komodo-era workflow, keep deploy.sh as break-glass
- Gitea webhook already wired to Komodo build endpoint
