Redesign the Active Downloads UI with four improvements:
- Rich progress: BullMQ jobs now report downloadedBytes/totalBytes instead
of just a percentage, showing "2.3 GB / 5.1 GB" instead of "78% / 100%"
- Friendly names: dispatch title metadata from curated categories, Content
Explorer library, Wikipedia selector, and map collections
- Cancel button: Redis-based cross-process abort signal lets users cancel
active downloads with file cleanup. Confirmation step prevents accidents.
- Live status indicator: green pulsing dot with transfer speed for active
downloads, orange stall warning after 60s of no data, gray dot for queued
Backward compatible with in-flight jobs that have integer-only progress.

Failed download jobs persist in BullMQ forever with no way to clear
them, leaving stale error notifications in Content Explorer and Easy
Setup. Adds a dismiss button (X) on failed download cards that removes
the job from the queue via a new DELETE endpoint.
- Backend: DELETE /api/downloads/jobs/:jobId endpoint
- Frontend: X button on failed download cards with immediate refresh
