Using the same class that's used to list media when rendering
pages ensures a consistent experience. The goal here was to avoid
listing image alternatives, but retain all the files available
through $page->media()->all()
* Always delete image alternatives in AdminController#taskDelmedia
Previously, image alternatives would only be deleted if the base
image wasn't found, and only the first three alternatives would
be removed. This commit changes that, so that all image
alternatives are always deleted when the base image is.
* Remove use of $deleteCount in AdminController#taskDelmedia
Press Ctrl+S when editing a page does trigger a save prompt, however,
the content is not saved.
This was broken because Remodal changed their DOM structure in commit
461d5ec307a3214e0d2c1427b613178236ed9293, which caused the
"remodal-overlay" not to be a parent of the "Continue" button.
This commit updated the selector to rely on the DOM structure we
control, so that hopefully it will not break again if Remodal changes.
