UI-Feinschliff Buchungen: Tarife oben, Credits darunter, Preisliste, USt.-Modal

- Reihenfolge: Tarife -> Einzel-PM -> Credit-Wallet & Add-ons -> Preisliste
- Buchungs-Bestaetigungs-Modal mit USt.-Aufschluesselung (netto/USt./gesamt,
  Reverse-Charge & steuerbefreit) vor Stripe; greift fuer Tarife, Einzel-PM
  und Credit-Pakete (selectBooking)
- Proaktiver Banner oben, wenn die Rechnungsadresse fehlt (Link ins Profil);
  im Modal Adress-Gate statt Stripe-Link
- Extra-PM-Karte nur bei Guthaben > 0 oder aktivem Abo (sonst Preisliste)
- Pruefkontingent ausgeblendet (Phase 2)
- Preisliste: Extra-PM nach Tarif (eigener Tarif markiert), Boost-Laufzeiten,
  Nachweis-PDF
