feat(web): Improved assets upload (#3850)

* Improved asset upload algorithm.

- Upload Queue: New process algorithm
- Upload Queue: Concurrency correctly respected when dragging / adding multiple group of files to the queue
- Upload Task: Add more information about progress (upload speed and remaining time)
- Upload Panel: Add more information to about the queue status (Remaining, Errors, Duplicated, Uploaded)
- Error recovery: asset information are kept in the queue to give the user a chance to read the error message
- Error recovery: on error allow the user to retry the upload or hide the error / all errors

* Support "live" editing of the upload concurrency

* Fixed some issues

* Reformat

* fix: merge, linting, dark mode, upload to share
