v6.8: Stopp-Button Fix, persistente Freitext-Lieferant-Speicherung, SW-Update

- Stopp-Button: overflow:hidden auf Video-Container, z-index auf Controls,
  pointer-events:none auf Quagga-Canvas damit der Button klickbar bleibt
- Freitext-Lieferant wird persistent in localStorage gespeichert (hbs_config)
  und bei Dropdown-Aenderung sofort aktualisiert
- Service Worker: Network-first fuer eigene Assets (JS/CSS), Cache-first
  nur noch fuer CDN-Libraries
- Letzte Bestell-ID (lastOrderId) ebenfalls persistent
- Migration alter localStorage-Keys in neue zentrale Config
