hub v0.74.0: allow local_api_endpoint_drift; R-77 docs + R-78/79/80

The allowlist entry is REQUIRED, not cosmetic: handleEvent 400s an unknown
event_type, so controller v0.173.0's new drift alert would be silently inert
without it. Shipped with the controller that emits it.

Docs:
- RUNBOOK-local-api-endpoint-drift.md — how to repair a drift, including the
  step everyone will want to skip (establish which value is CORRECT from what
  the agent is actually bound to, rather than assuming bootstrap.json wins) and
  what success looks like (SILENCE, not a "recovered" line, because a fresh
  controller's healthy first observation is not logged). Records both
  2026-07-26 repairs.
- ROADMAP: R-77 shipped; R-78 the local_api authority ruling, with the
  clobber-a-working-channel risk spelled out in BOTH directions so it is not
  resolved opportunistically; R-79 the whole-surface English-strings sweep;
  R-80 expected_backup_missed, flagged as likely outranking R-77 because 7.3
  days of stale backup materially exceeds the ~1.5-day channel outage, so the
  causal link the DIAG hedged on cannot be the whole story.
- Capability map: note against the drive-wizard row (every agent-backed
  capability rides this channel) that a silent drift class is now detected.
  NO row status flips — detection is not prevention.

No row status flips.** `controller.yaml` and `bootstrap.json` could disagree on `local_api.endpoint` indefinitely with no signal: the R-50 island migration rewrote the latter, the fleet kept dialling the former, and for 17.5 h the only alert was a generic "agent unreachable" that read as an infrastructure blip. Drift now raises its own event type (`local_api_endpoint_drift`) naming both values. It is DETECTION ONLY — the authority ruling is R-78 — so the class is now loud, not prevented.
