The hidden field in blog posts reverts to the original value when toggled

When toggling the hidden field on a blog post, the value is reverted. See the canthide.mp4 attachment.

The hidden field is used by the blog application for the published status, so an unpublished article can be hidden away from several places.
See https://github.com/xwiki-contrib/application-blog/commit/99c756831cae3dab73f2f1aa491356872a610320#diff-ac3b5f3b6617fe2507b5745ebf2fcf0a9300f810754bdf075dedd5c55c358565

Expected: any of

• The hidden field is not editable and a help message says that one should use the blog application to (un)publish an article
• Toggling the hidden field (un)publishes the post (and makes it clear with a notification / a message).
  • "hidden" should perhaps be displayed as "unpublished" for blog posts to warn the user that hidden has specific behavior here
