fix(lint): Add ctx shim to routes/apps and routes/arr

- routes/apps/deploy.js: Add ctx shim with APP_TEMPLATES, siteConfig, buildDomain, buildServiceUrl, addServiceToConfig, dns, notification, safeErrorMessage
- routes/apps/index.js: Extract additional ctx properties for sub-routes
- routes/arr/config.js: Add ctx shim with notification, safeErrorMessage + logError import
- routes/arr/index.js: Extract notification, safeErrorMessage for sub-routes

Result: Fixed ~30 no-undef errors (deploy.js 0 errors, arr/config.js 0 errors)
