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.

The Dashboard's "Retry All Failed" button used to fetch every non-superseded
failure, then fire one retry HTTP call per row. Two missing guards:
- No per-source dedup — a source with N historical failures enqueued N jobs
for the same URL.
- No "recent success" check — a source that succeeded two hours ago could
still have stale un-superseded failures from last week that got re-queued.
Adds POST /api/downloads/retry-failed-bulk:
• Selects non-superseded failures, ordered (source_id ASC, created_at DESC)
• Per-source dedup keeps only the most recent failure per source
• Skips sources whose last_success is within the configurable recent window
(default 24h, via recent_window_hours body param)
• Resets + enqueues in a single DB transaction, single Celery dispatch loop
• Returns a per-reason skip breakdown: duplicate_source, recent_success,
no_source (orphaned rows)
The Dashboard button now calls the bulk endpoint and surfaces the full
skip breakdown in the toast, so the user knows exactly what was (and
wasn't) queued. Logic is extracted into a pure _plan_bulk_retry helper
and unit-tested against SimpleNamespace fixtures — 7 new tests covering
the dedup, window, and orphan paths.
Converts the Source Health last-check column and the Downloads created-at
column from locale date strings to human-relative times ("6 hours ago").
The absolute timestamp is preserved as a native browser tooltip so full
precision is still one hover away; detail modals keep the absolute form.

Replace all bare `session = AsyncSession(bind=conn)` assignments with
`async with AsyncSession(bind=conn) as session:` in downloads.py,
credentials.py, settings.py, sources.py, and subscriptions.py to
ensure sessions are properly closed on all code paths.
