fix: pass screenShareEncoding to override LiveKit's 15fps default

Browse Source 
LiveKit uses screenShareEncoding (not videoEncoding) for screen share
tracks. Without it, both primary and backup fall back to the default
ScreenSharePresets.h1080fps15 (15fps). Primary was masked by our
overdrive mechanism, but backup had no overdrive and was stuck at 15fps.
