feat(backend): implement custom services CRUD handlers
Add 6 admin endpoints for custom services: list (with search/popular/pagination), create, get, update, promote to regular service, and delete. Each handler validates admin role via middleware. Ultraworked with Sisyphus (https://github.com/code-yeongyu/oh-my-openagent) Co-authored-by: Sisyphus <clio-agent@sisyphuslabs.ai>
