[Feature Request]: Option to delete all channels with zero videos

I've read the documentation

• I have read the how to open an issue guide, particularly the feature request section.

Your Feature Request

Is your feature request related to a problem? Please describe.

After deleting a very large playlist, including all its videos, I was left with hundreds of channels that are now empty.

It would be nice to have an option to launch a clean-up operation that automatically deletes all channels that no longer have any videos linked to them. Otherwise, each channel would have to be deleted by hand.

Describe the solution you'd like

• Add a button to the Settings/Action page to clean up empty channels (and maybe playlists too if applicable).

Additional context

None

Your help is needed!

• Yes I will work on this in the next few days or weeks.
