In media lists, move "Hidden buttons" from "Buttons type" to its own category

Feature description:

This is somewhat related to this issue.

Make it so users are able to toggle certain buttons within media lists, not unlike what is already possible for other pages (Album page, Artist page, etc.)

This seems to be traditionnaly done under the “Hidden buttons” category, which should also imply the removal of the “Hidden” option for the already present “Buttons type” category.

Problem solved:

Users are currently unable to remove buttons they deem less useful, leading to a needlessly cluttered interface.

Brought benefits:

More granular personalization for users.
Falls in line with other pages’ customization.

Other application solutions:
