fix(gamepad): working per-session SwDeviceCreate for the Windows DualSense

Browse Source 
create_swdevice now succeeds. The two requirements (each E_INVALIDARG otherwise): the
enumerator name must have no underscore (use "punktfunk"), and the completion callback is
mandatory (the docs mark pCallback [in], not optional -- NULL is rejected). Back on the
typed windows-rs SwDeviceCreate (a raw-FFI diagnosis confirmed it's the OS, not the
binding), parameterized by pad index (instance pf_pad_<index>), waiting on the callback.
Per-session device: created on connect, SwDeviceClose'd on drop -- no leftovers, no phantom.

Live-verified on the RTX box: device materializes, the UMDF driver binds, SDL3 identifies it
as a PS5 ("DualSense Wireless Controller"), input flows; removed on disconnect. The
dualsense-windows-test CLI now cycles input + prints any 0x02 feedback for diagnosis.
