The feature

When editing faces, show clickable boxes around all tagged faces in the image.
For example, in Google Photos, opening the "Edit faces" view shows little clickable circles around every recognized face, which can be clicked to edit that face, as well as clicking on a face in the list view on the side/bottom.
This would be a great addition to immich. Much like how hovering over a face in the People list shows a box around the person's face, after clicking the Edit button in that view it would be helpful for it to highlight all faces in that image. This is especially helpful in group settings where I'm trying to make sure everyone's face has been found (manual tagging is amazing for filling in the gaps, but it's difficult to see at a glance who does/doesn't have a face).

Note that this is not a duplicate of #3489 as that one still only refers to one face at a time, where I'm asking for all faces to be shown at once. (Referencing this one in particular because it was the only mildly similar discussion that popped up when I attempted to locate similar/existing posts)
