Fit the login form to the picture's box

The form now sits in the same 16:9 box as the snapshot, so a card keeps
its height whichever it shows. A compact variant drops the aside about
which user to create and tightens the spacing, since that space is fixed;
the camera page keeps the full form, where there is room. Anything that
still doesn't fit scrolls inside the box rather than stretching the card.
