Fix Qdrant API endpoint registration and implement missing stats endpoint

Fixed 404 errors for Qdrant endpoints by ensuring config parameter is properly passed:
- Updated createServer() in server.ts to accept config parameter
- Updated createRouter() call in index.ts to pass config parameter
- QdrantEndpoint now properly registers when config is available

Implemented missing /api/qdrant/stats endpoint:
- Added getSystemStats method with proper error handling
- Returns system-wide statistics: collections, vectors, enabled shops, etc.
- Matches API documentation format with success/data structure

Both /api/qdrant/health and /api/qdrant/stats endpoints now work correctly.
Frontend 404 errors resolved for production deployment.
