Add project routing with storage and worker backends

Migration 21:

- Add project_routes with primary key on (project_id, pattern)
- Support storage and worker backend types
- Add triggers to sync main worker and project names
- Add resolve_worker_from_request() for unified routing

CLI:

- Fix URL formatting based on backend type

Related changes:
