Pull Request

Description

This PR implements recursive folder deletion logic for the object browser. Previously, deleting a folder required the frontend to manually traverse and delete each file, which was inefficient and could lead to UI freezes.

Key changes:

• Introduced a new delete-folder task type in delete-task.ts that handles recursive deletion on the backend/SDK side using ListObjectsV2 and DeleteObjects .
• Updated task-context.tsx to support dispatching folder deletion tasks.
• Refactored list.tsx to use the new task-based deletion for both files and folders.
• Added an auto-refresh mechanism in the object list that triggers once all active delete tasks are completed.

Additional Notes

The recursive deletion supports both versioned and non-versioned buckets. For versioned buckets, it correctly handles the deletion of all object versions when the "Delete All Versions" option is selected.
