Update MinIO bucket configuration and enhance dashboard service caching

- Changed the default MinIO bucket name from "opplens-documents" to "opplens" across multiple configuration files.
- Introduced caching for dashboard statistics in the service layer to improve performance and reduce redundant data fetching.
- Implemented a mutex for thread-safe access to cached statistics, ensuring data integrity during concurrent requests.

This update streamlines the configuration for the AI summarizer and optimizes the dashboard service, enhancing overall system efficiency.
