fix: health endpoint at /api/health, docker-compose.dev.yml DATABASE_URL, worker env_file

- Move Express health route from /health to /api/health so it works
  behind Caddy proxy that forwards /api/* unchanged (not handle_path)
- docker-compose.dev.yml: remove DATABASE_URL from api-dev and worker-dev
  environment blocks — .env.dev provides the correct value and env_file
  already loads it
- docker-compose.dev.yml: add env_file to worker-dev so it gets
  DATABASE_URL from .env.dev
- docker-compose.dev.yml: fix healthcheck from /health to /api/health
- packages/api/src/worker/index.js: remove duplicate env section
  (env vars are now correctly provided by docker-compose)
