Improve data fetching performance and fix fast refresh issues

Refactor `fetchData` in `ManufacturerModels.tsx` using `useCallback` to prevent unnecessary re-renders and memoize the function. Add `fetchData` to the `useEffect` dependency array in `ManufacturerModels.tsx` to ensure it's correctly called. Address Fast Refresh compatibility in `useAuth.tsx` and correct `setInterval` dependency in `useModerationQueue.ts`.
