Add queue management dashboard (#15202)

Adds a comprehensive queue management interface to the admin panel for
viewing and managing background jobs.

**Features:**
- Queue detail pages showing paginated job lists (50 per page)
- Filter jobs by state: completed, failed, active, waiting, delayed,
paused
- Checkbox selection with bulk actions (delete jobs, retry failed jobs)
- Per-job dropdown menu for individual retry/delete
- Expandable rows showing error messages, stack traces, and job data
- Relative timestamps with hover tooltips
- Display attempt counts on failed jobs
- Dynamic retention policy info from backend

**Changes:**
- Backend: New AdminPanelQueueService with GraphQL endpoints for job
listing, retry, and delete
- Frontend: Queue detail page with QueueJobsTable component
- Updated retention policy: completed jobs kept 4 hours, failed jobs
kept 7 days (max 1000 each)
- Added JobState enum for type safety
