Add keyboard control for a dealer working on a laptop

The phone got gestures a few rounds back; the desktop still had a mouse and nothing else. On a bar that gets tapped thirty times a hand, moving a hand to the trackpad between every decision is the slow part. F folds, C checks or calls, R opens the raise pad, A shoves, Enter confirms a raise or moves the hand on, Esc backs out, U takes the last action back. Each button wears its key in the corner, hidden on touch devices where it would just be clutter on a button being tapped anyway. The shortcuts press the same buttons a dealer would tap rather than calling the betting engine themselves, so there's no second code path to drift out of step with what the bar is actually offering — if a button isn't on screen, its key does nothing. Nothing fires while a name, amount or note is being typed, or while an overlay owns the keyboard. Typing "Francesca" into a seat name must not fold the table.
