Converted routes: - All auth routes (totp.js, keys.js, sso-gate.js) - Recipe deployment routes (deploy.js, manage.js, index.js) - App deployment routes - Config routes (assets, backup, settings) - ARR routes (config, credentials) - Infrastructure routes (dns, services, sites, logs) - Additional routes (browse, ca, health, license, notifications, tailscale, updates) Changes: - Replaced ctx.errorResponse() with throw statements - Replaced errorResponse() with throw statements - Added proper error imports to each file - 400 errors → ValidationError - 401 errors → AuthenticationError - 403 errors → ForbiddenError - 404 errors → NotFoundError - 409 errors → ConflictError - 500 errors → Handled by middleware Result: 25 files migrated, ~150 error responses standardized
