fix(gamepad): truncate stick/trigger axes uniformly across clients (G25)

Browse Source 
Apple's GamepadCapture rounded axis values (`(v * scale).rounded()`) while
SDL-core and Android truncate, so a half-pressed control emitted 128 on Apple
vs 127 elsewhere. Drop `.rounded()` so `Int32(Float)` truncates toward zero on
Apple too; rails are unchanged (full deflection stays 255 / ±32767).

Also clamp SDL-core's LeftX/RightX to a symmetric -32767 like the Y axes and
the other clients already do, instead of letting the raw i16 reach -32768.

Verified: Apple `swift build` + full PunktfunkKit suite (124 pass); SDL half
on Windows .173 `cargo clippy -p pf-client-core -- -D warnings` (green).
