Fix status/active mirror drift in upsert_sources (pre Promote-candidate)

Per Codex: upsert_sources() wrote `active` but not `status`, so a candidate
promoted inactive (the pipeline default) became active=0 + status='active' —
the exact mirror drift Phase 1 set out to avoid (scheduler won't poll, admin UI
shows "active"). Now derive status from an explicit value or from active, mirror
active off status, and write both columns together (insert + conflict update).
Test: promote_candidate(active=False) → status='paused', active=0.

Also fix stale source_health docstring (now includes retired).
