All three trigger-indexing routes were calling service.createIndexingJob()
directly which only inserts the DB record but never calls processNext().
Fixed to route through getQueue().enqueue() so the job queue actually
picks up and runs the job immediately.
Affected routes:
- POST /api/v1/libs (autoIndex on add)
- POST /api/v1/libs/:id/index
- POST /api/v1/libs/:id/versions/:tag/index
