Source_files bulk excluse/include functions implementation

[ruwinirathnamalala]

feat: Add bulk exclude/include functionality for source files

Implemented bulk operations to exclude/include multiple source files simultaneously with optimized processing and improved user experience.

Backend Changes:

• Created bulk-exclude endpoint (DSL/Ruuter/ckb/POST/source-file/bulk-exclude.yml)
• Added update_source_files_exclude_batch.sql with array handling via json_array_elements_text
• Implemented conditional path transformation for exclude/include operations
• Added WHERE clause to skip files already in desired state (performance optimization)
• Switched to async file moving (/move-files-async) to prevent timeout errors
• Created DMapper templates for S3 path transformations (exclude/include)

Frontend Changes:

• Added bulk include/exclude actions to multiselect menu
• Implemented bulkUpdateFileExclusion API service
• Added confirmation dialogs with file count display
• Implemented client-side filtering to only send files needing state change
• Added info toast notifications when all files already in desired state

Technical Improvements:

• Dual-layer optimization: frontend filters before API call, SQL filters before DB update
• Async S3 operations prevent ReadTimeoutException on large batches
• Proper error handling with user-friendly messages
• Row selection cleared after successful operations

Resolves timeout issues and unnecessary database updates for bulk file operations.
