fix(shopfloor,reports): scanner status line + sticker rev cleanup

- Re-detect BarcodeDetector / window.jsQR at every modal open instead
  of only at component setup. Avoids the trap where a stale cached
  bundle reports "no decoder" even after a redeploy.
- Add a one-line status indicator at the top of the scan modal showing
  exactly which decoder is active ("Decoder: native" / "Decoder: jsqr"
  / "Decoder: none — paste URL below"). Lets the operator see at a
  glance whether scanning is even possible without round-tripping
  through Safari Web Inspector.
- Sticker: strip a leading "Rev " (case-insensitive) from
  fp.part.catalog.revision before printing so values like "Rev 1"
  don't render as "Rev Rev 1".

Versions: shopfloor 19.0.18 -> 19.0.19, reports 19.0.7.16 -> 19.0.7.17.
