fix(render+admin): render queue shows ALL users' jobs

The admin render queue called the user-scoped /v1/renders (so it only showed the
admin's own jobs) and parsed items/total instead of data/meta (→ always empty).
- render-svc: GET /v1/admin-renders (admin) → ListAllJobs across users, optional
  ?status= filter; gateway-wired
- admin renders page now fetches /v1/admin-renders and reads data/meta correctly
