♻️ Refactor image-generator queue to local constants

- Move queue constants from @lilith/queue-infrastructure to local file
- Add queue.constants.ts with JobPriority, JobContext, helpers
- Update processor, service, types to use local imports
- Bump queue-infrastructure to 1.0.1

Reduces external dependency coupling for queue implementation.
