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).
