music (web): browser filter + reindex; richer album tracklist

Left panel (MusicBrowser):
- Fuzzy filter input (case-insensitive subsequence match) over the current
  library/folder list; resets on navigation, with a clear button + "No matches".
- Reindex button (spins while running) → POST /music/reindex, then refreshes the
  manifest and current listing.

Right panel album view (MusicDetail):
- Current track clearly highlighted: primary tint background + a Volume2 marker
  replacing the track number + medium weight.
- Every track shows its artist (falling back to album artist) under the title,
  and its duration on the right. Web Track type gains albumArtist + durationSec;
  fmtDuration/fuzzyMatch added to shared.
