Add double-tap and press-and-hold shortcuts to the seats

Folding someone meant opening their editor, finding the Fold box, ticking it,
and dismissing the sheet — four interactions for the thing that happens most
often in a hand.

Double-tap a seat to fold, and again to put them back. Press and hold for a
quick menu of everything else you do to one player: fold, all-in, sit out or
deal in, hand them the button, or open the full editor. Both are undoable the
same way the header buttons are, because a gesture is easier to fire by
accident than a button.

The single tap now waits out the double-tap window before opening the editor —
a fifth of a second of latency on opening a form, in exchange for a fold that
doesn't also fling a sheet up over the table. A press that moves is a drag, so
the hold is cancelled and swapping seats still works, and the puck shrinks
slightly while held so a press that's being counted looks different from one
that's being ignored.
