The gamepad-UI navigation resolvers disagreed on which way a perfect 45-degree
stick push (|x| == |y|) resolves: the SDL core picked horizontal (`ax >= ay`)
while Apple (`abs(x) > abs(y)`) and Android (`abs(Y) >= abs(X)`) picked vertical.
Align Apple (`>` -> `>=`) and Android (`>=` -> `>`) to the SDL core so an exact
diagonal moves focus the same way on every client (horizontal wins). This is
client-local menu navigation only and never reaches the wire. Completes the last
deferred G25 sub-part.
Verified: Apple `swift build` + full suite (124 pass); Android `:app:compileDebugKotlin`.
