Turn the Sources tab into a real management console (per Codex):
* source_health now lists ALL sources (active + paused) with backing metrics:
served / accepted_total / total_articles / duplicates + acceptance & duplicate
rates + review_reason, alongside last success/attempt, next poll, failures.
* Admin endpoints (gated, 404 on missing): POST sources/{id}/active (pause/
resume) and /review (flag/clear with reason).
* Pausing only stops future polling — the feed query has no active filter, so a
paused source's accepted articles stay live.
* Frontend: metric table + Paused filter + per-row Pause/Resume & Flag/Clear
(optimistic, revert on failure). Attention 'resting' now scoped to active.
Retire/Delete intentionally deferred (distinct lifecycle state, later).
