docs: website cutover runbook + post-execution status snapshot

Captures the agreed cutover plan (Q6 in the decisions log: double-write
transition window, ~30 days, then NocoDB decommission). The CRM side
is wired today — public berth feed, website-inquiries intake, dual-mode
health probe, WEBSITE_INTAKE_SECRET env var. The runbook documents the
website-repo checklist and rollback path so we can pick it back up
when prep for prod begins.

Refreshes the audit-followups status snapshot to reflect what shipped
this session. Wave 11 is now broken out into A-G subitems so the
remaining group-discussion work is enumerated rather than collapsed.

Note: .env.example separately needs WEBSITE_INTAKE_SECRET added (see
runbook §Endpoints). The husky pre-commit hook blocks .env* files
intentionally — pass via a separate workflow.
