Migrate CI to single-step DinD with Fabio/Consul

Replace 5-step pipeline (build/test/push/push/deploy) with single
docker:dind step that builds and deploys in-place via Docker socket.

- .woodpecker.yml: single-step DinD, 1 secret (SECRET_KEY)
- docker-compose.fabio.yml: overlay with SERVICE_* labels for Registrator
- docker-compose.yml: add ports without host bind (Fabio/Traefik routing)
- docker-compose.dev.yml: named volumes with bind driver
- Dockerfiles: install curl, HEALTHCHECK via curl /api/health
- Makefile: docker-fabio, consul-services, fabio-routes targets
