Confirm hand refresh visually in Deep Upkeep

After a resting Deep player confirms their hand refresh, replace the
discard/keep drag editor with a confirmation panel showing the freshly
drawn hand and a "Waiting for the rest of the crew" message, instead of
re-rendering the editable drag UI (which made it look like nothing
happened). Also stops nagging "please complete your Hand Refresh" once
they're done. Visible whenever they remain in deep_upkeep waiting on
other resting Deep players.
