fix: add FavQ and TopQ context types to playback context

The ContextType enum and v2_set_playback_context match were missing
fav_q and top_q variants, causing an "Invalid context type" error that
blocked all playback from FavQ and TopQ views. Also wrap
setPlaybackContext calls in try/catch so context errors don't prevent
track playback.

Fixes #140
