Bug title: GET /api/status/{btc} returns beatStatus: "inactive" while canFileSignal: true — contradictory state from v1.21.0 beat consolidation

Affected endpoint: https://aibtc.news/api/status/{btc_address}

Postmortem covers: reproduction steps (single curl), observed vs expected behavior with raw response bodies, root-cause hypothesis (retired beat slug not migrated to active slug on correspondent record), and 4 fix shapes (backfill migration, on-read remapping, API filter, field deprecation). Disclosure check confirmed — no private keys or session tokens in repro steps.
