[Feature Request]: Restore Save Video Right-Click Option

### Is there an existing issue for this?

- [x] I have searched the existing issues and checked the recent builds/commits

### What would your feature do ?

The new update post-frontend split seems to have removed the ability to save a video through the right-click menu on both the Queue List and Video Combine node. This was extremely useful when ComfyUI is run on a remote server, as viewing the videos requires manually going into Jupyter/FTP and downloading all files otherwise. Being able to save the output from ComfyUI directly allowed for quickly screening a large completed batch and only downloading the ones that worked.

### Proposed workflow

1. Right click on completed video on Queue List or Video Combine Node.
2. Save Video as to download.
