feat: Flasche und Maske als Kleidung, Patronen tauschen, HUD-Anmeldung

- Tauchgeraet bereit = Taucherflasche (rigItem, Slot 31) mit Patrone UND
  Maske (maskItem, Slot 29) angezogen; Server getWorn statt verifyGear,
  geprueft bei jeder Inventaraenderung und nach jedem Umziehen.
  Props, diving_gear und der Anzieh-Balken entfallen.
- Die fuenf Flaschen sind Patronen: benutzen = in die getragene Flasche
  einsetzen, die alte kommt mit Restluft zurueck (patroneTauschen).
- Faeden mit Laufnummer, damit ein Tausch sie nicht verdoppelt.
- exports.ox_inventory -> exports.d4rk_inventory, Meldungen ueber
  lib.notify (meldung_shared) und d4rk_bridge:Notify.
- Konsole beim HUD angemeldet (client/hud.lua), 366 x 165 bei 1080p
  gemessen; ohne HUD bleibt die CSS-Position.
- Nachfuellen (diving_fill) stillgelegt: kommt spaeter ueber Shop/Crafting.
