Problem/Motivation
The uninstall box for Layout Builder is grayed out with the message
The Layout Section field type is used in the following field: node.layout_builder__layout
The "Manage Fields" page shows the Layout field as locked.
The "Manage Display" page says
You must revert all customized layouts of this display before you can disable this option.
Without individually checking each node, there is no way to determine which must be reverted
Proposed resolution
Several options:
1) A page under /admin/reports (linked from Manage Display?) similar to the Field List that shows all overridden layouts, with a revert option (or bulk operation?)
2) A "Revert All" button on Manage Display that works for only that single bundle (probably behind a confirmation form?)
3) ???
Remaining tasks
