haptics: recognize 'Wireless Controller' audio endpoint on Linux (#1046)

Browse Source 
On Linux (PipeWire / ALSA), the 4-channel USB audio playback device for
the DualSense controller is named 'Wireless Controller' based on Sony's
USB product descriptor string. Previously, FindDevice() only matched
names containing 'DualSense', causing quad-channel endpoint discovery to
fail on Linux systems.

Add 'Wireless Controller' to the allowed endpoint names when 4 channels
are present, and add a test case verifying discovery under this name.
