ignacionelson a5b6538b31 Give folder sharing and the folder-delete guard one definition each
Sharing a folder was four steps written in the web controller: the
assignment row, the activity entry, the in-app notification and the
digest email. The hosted edition's AI connector repeated them, because
there was nothing in the core to call, and the two copies had already
drifted (one re-notifies on a repeated share, the other does not). The
folder API about to land would have been a third copy.

FolderSharing is the folder twin of FileSharing, and the web controller
now calls it. Behaviour on the web is unchanged.

The count of files a staff member may not delete inside a folder's
subtree moves out of FoldersController into UndeletableFiles, for the
same reason: deleting a folder over the API has to ask exactly the
question the web screen asks before the cascade takes files with it.

* What actually happens when a folder is shared with a client or a group —
* the assignment row, the activity entry, the in-app notification and the
* debounced digest email, in that order. The folder twin of FileSharing.
*
* Extracted for the same reason FileSharing was: the web controller and the
* API controller must not be able to answer the question differently. The
* AI connector in the hosted edition repeated these four steps too, because
* there was nothing here to call.
*
* Unlike a file, a folder has no scan to wait for: the files inside it are
* held back individually until they can be had, and sharing the folder
* does not change that. So the telling is never deferred here.
*
* Authorization is the caller's job — both callers reach this after
* Gate::authorize('update', $folder), and the target has already been
* resolved and scope-checked by ResolvesShareTargets.
