Per Codex — a per-row Check button that previews a LIVE source on demand,
intentionally read-only and ephemeral.
* POST /api/admin/sources/{id}/preview — admin-gated, safe-fetch + heuristic
preview (reuses the candidate preview path), returns the result. Mutates
NOTHING: no DB write, no poll attempt, no health/state change. 404 on missing.
* UI: per-row Check button with a Checking… state; results in an inline row
under the source (sampled, would-pass %, recent-7d, example accept/skip
headlines) with dismiss; inline error on failure. "Checked just now" is
local UI state only. Heuristic v1 — model deep-check left for later.
