Redesigned WAV Browser as a structured Sample Library with card layout:
- WAVs grouped by library (ISO name) and program (volume name)
- Library cards with collapsible headers showing program/sample counts
- Program sections within each library
- Sample cards in a compact grid with play-on-click
Updated playWav to show a clean sample name in the player bar,
hide the player when playback ends, and use sample-card selectors
for active-state highlighting.
Clean display names (underscores → spaces, stripped .wav extensions)
