feat: complete Qdrant store mechanism with webhooks and background scheduler

- Add comprehensive webhook events for Qdrant and MCP operations
- Implement QdrantEmbeddingWorkflow with webhook notifications
- Create SchedulerService for background cleanup and health monitoring
- Add scheduler management API endpoints
- Integrate webhook notifications into embedding process
- Add database cleanup methods for logs and errors
- Complete embedding batch processing with webhooks
- Add MCP tool failure notifications
