Merge vr-library (Steam library art, Play/Stop, refresh-art) into the store

Resolve CLI usage and POST table conflicts. Store installs now hand the
source's own image URLs (icon, banner, screenshots) to frame_android.install
as Steam artwork; before, they passed UI proxy paths (or nothing), so every
store install fell back to generated art.
