feat(fe): implement working ModelsList grid with mock data

- Simplified data fetching (removed TanStack Query for now)
- Added direct mock API client in component
- Fixed state management (isLoading, isError, modelsData)
- Grid now renders with 3 sample model records
- Updated v-if conditions for loading/error/empty states
- Added grid container height and filter styling
