- updateCheckService: gate the external request on `update_check_enabled`
(default on); when off, no network call, returns { disabled: true }
- aboutAdmin: GET/PUT /update-check-setting (admin-only) to toggle it
- StatusPage: a Switch on the admin System Status card to enable/disable
- privacy.js: state that an admin can disable it (was called "optional" with
no actual opt-out)
- tests/updateCheckOptOut.test.js: proves no external fetch when disabled
- docs: archive QA-B16-01, B16 ✅

CRITICAL fix: Users upgrading from pre-migration-tracking databases
(now get 'invalid username/password' because schema_migrations table
doesn't exist. Added handleLegacyDatabase() and
reconcileLegacyMigrations() to detect and reconcile legacy DBs.
Security fixes:
- Path traversal: replaced sanitizePath() with ALLOWED_FILES allowlist
- Public /about bypass: added admin route guard in App.jsx
- Sensitive info exposure: expanded redactSensitiveContent() patterns
- Error message path leaks: generic error messages only
- Race condition: wrapped in db.transaction() in server.js
- Password validation: INIT_REGULAR_PASS min 8 chars with process.exit(1)
All verified by Bishop (build + runtime) and Private_Hudson (security).
