Bet/Raise now opens a sheet whose presets follow the spot: open sizes
in BB (adjusted for limpers), 3bet/4bet multiples, postflop pot
fractions and raise multiples. Adds -/+ steppers with hold-to-repeat,
Min/All-in at the slider ends, and a square-curve slider so small sizes
stay precise with deep stacks. The hand view now exposes the street's
raise count so the client can tell a 3bet from a 4bet.
