When using the `admin.hidden: true` property on a collection, it
rightfully removes all navigation and routing for that particular
collection. However, this also affects the expected behavior of hidden
entities when they are rendered within a drawer, such as the document
drawer or list drawer. For example, when creating a new _admin.hidden_
document through the relationship or join field, the drawer should still
render the view, despite the underlying route for that view being
disabled. This change was a result of the introduction of on-demand
server components in #8364, where we now make a server roundtrip to
render the view in its entirety, which include the logic that redirects
these hidden entities.
Now, we pass a new `overrideEntityVisibility` argument through the
server function that, when true, skips this step. This way documents can
continue to respect `admin.hidden` while also having the ability to
override on a case-by-case basis throughout the UI.
