Subject: [PATCH] feat(dashboard): revamp with at-a-glance strip, sparkline,
 modal, disk bar
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace the four stat cards with a compact three-card strip: 7-day activity
with inline SVG sparkline (new ActivitySparkline), Running Now / Next Check
with per-source countdown list, and System with credential health + disk
usage bar.

- Add GET /downloads/activity-timeline — per-day completed/failed/files
  counts, pre-filled with zero buckets so the sparkline always has N points.
- Report filesystem-level usage via shutil.disk_usage in storage rollup,
  plus a live fallback in GET /settings so the capacity bar works before
  the first Celery rollup runs and for cached rows that predate the field.
- Extract Download Details into a reusable DownloadDetailsModal component
  and wire Recent Activity rows to open it (previously Downloads-page only).
- Compute next scheduled check per source from global schedule_interval;
  surface credential expiration/missing alerts scoped to platforms that
  actually have enabled sources.
- Two-speed polling (5s when downloads are active, 30s idle) with Page
  Visibility awareness so background tabs don't churn the API.
