audit: 33-agent comprehensive audit + critical fixes

Full team audit run, all reports verbatim in docs/AUDIT-2026-05-12.md
(5900+ lines, 30+ critical findings). Already-fixed this commit:
- permission-overrides PUT: self-target block + RolePermissions allow-list + cross-tenant guard
- /api/auth/resolve-identifier: rate-limit + synthetic miss-email kill enumeration
- admin email-change: rotates account.accountId + revokes sessions
- middleware: token-gated email confirm/cancel routes whitelisted
- NAV_CATALOG: 10 dead-link sweeps to existing /admin/<x> targets

Feature work landing same commit: optional username sign-in
(migration 0054), per-user permission overrides (0055) with three-state
matrix tabbed inside UserForm, user disable button, role + outcome +
stage label normalisation across the platform, admin email-change
with auto-notification template.
