Merge branch 'Shipping-Build-Overhaul'

Refactorise l'accès aux interfaces Direct3D pour plus de clarté et d'efficacité, en utilisant des accesseurs `const` et en déplaçant certaines fonctions directement dans l'en-tête.

Cela simplifie l'utilisation des ressources D3D et améliore la lisibilité du code.
