feat(deploy): build + serve worker and admin as static nginx images

- per-app Dockerfiles (vite build → nginx) + SPA nginx.conf
- Gitea workflow pushes 3 images; frontends bake VITE_API_URL
- docker-compose.prod.yml (registry images, solelog_network) + .env.prod.example
- docker-compose.yml runs the full stack locally; add .dockerignore

.gitea/workflows/docker.yml
