feat: update knowledge base file detail view with pagination and metadata display

[Dallas98]

This pull request consolidates the management of several optional services (Deer Flow, Label Studio, Milvus, Redis, Data Juicer) into the main deployment/docker/datamate/docker-compose.yml file using Docker Compose profiles. It removes their separate Docker Compose files and updates the Makefile to support the new unified, profile-based approach for installing and uninstalling services. Additionally, there are minor dependency and robustness improvements in the backend services.

Docker Compose and Service Management Refactor

• Migrated Deer Flow, Label Studio, and Milvus service definitions into deployment/docker/datamate/docker-compose.yml, enabling them as optional services via Docker Compose profiles. Their standalone Docker Compose files were deleted. [1] [2] [3] [4] [5]
• Added new profiles for Redis and Data Juicer, and updated the configuration for Mineru, making all these services optional and consistently managed through the main compose file. [1] [2]
• Updated Docker volumes and networks in deployment/docker/datamate/docker-compose.yml to support the new service structure.

Makefile and Install/Uninstall Logic

• Expanded VALID_SERVICE_TARGETS in the Makefile to include all new optional services and updated the Docker install/uninstall targets to use the unified compose file with profiles, simplifying and standardizing service management. [1] [2] [3]

Backend and Dependency Updates

• Added commons-io as a direct dependency in backend/pom.xml, and excluded it from a transitive dependency in rag-indexer-service/pom.xml to avoid conflicts. [1] [2]
• Improved robustness in RagEtlService.java by catching Throwable instead of Exception, ensuring all errors are handled during file processing.
