screenshare: advanced in-app streaming controls + hwdec toggle

Add a local-only "Screen sharing" section to Settings plus a per-call quality
picker on the Share control: in-app control over how a share is encoded
(quality/bitrate/framerate/max-height/max-viewers/software-x264, + extra
pixelpass args) and how it's played back (mpv/vlc, hardware decode, buffering,
cache, + extra mpv args). Settings live in AppConfig.screen_share (all
serde-defaulted, so old configs load unchanged) and become pixelpass host CLI
flags / mpv args at share/view launch.

Hardware decode defaults OFF, which also fixes the frozen-frame-with-audio bug:
forcing --hwdec=auto stalled some viewers' HW decoder on frame 1 while audio
kept playing.
