v4.1.1: pointer-first betting and visible payouts in the GUI

The felt snaps the hover to the shared fine lattice: inner half of a cell is a straight, an edge a split, a crossing a corner. A translucent chip previews the target and the covered cells tint. Left click adds the selected chip, right or middle click takes one back through the new Bets::reduce; C or CLEAR empties the slip, and SPIN stays disabled with no chips.

The result now pays out: the wheel leaves the winning pocket under the pointer, the winning cell and pocket get a gold outline, and the sidebar reports the amount returned and the net for the round (NO WIN on a loss). Placing a chip after a result starts the next round without losing the wheel position.

The column row now spans the full width like a real table instead of hugging the left edge. Adds tests for lattice snapping, target naming and taking chips back.
