jQuery UI as a project dependency.

I have created the RM, but I am waiting for changes added in other issues to be incorporated into the main project, so that I can avoid conflicts when doing the merge.

I've created a merge request with the proposed changes and would appreciate it if you could take a look when you get a chance.

Additionally, I suggest reviewing the logic related to date range validation. It seems that when trying to view a node, the page always returns a "403 Access Denied" error, regardless of the configured visibility dates. This might indicate an issue in how the date restrictions are being applied.
