feat: add Coolify deployment configuration

Add docker-compose.coolify.yml (17 services), .env.coolify.example,
and Gitea Action workflow for Coolify API deployment. Removes nginx,
vault, gitea, woodpecker, mailpit, and dev-only services. Adds Traefik
labels for *.breakpilot.ai domain routing with Let's Encrypt SSL.
