feat(dev): add compose files and dev-login bypass route

- compose.prod.yml: production stack with registry image, healthcheck,
  migration service
- compose.test.yml: local test stack with source mount and LOCAL=true
- routes/dev-login.ts: fake admin JWT login, only active when LOCAL=true
- routes/_middleware.ts: expose /dev-login as public route
