0978918f71 Fix Heap-buffer-overflow in Q3DImporter::InternReadFile (#6370) 
Checks if multiplying texture width and height would overflow before
performing the operation. This avoids incorrect memory allocations and
potential crashes with very large textures.

Fixes #6358

4c42db1805 Fixed a heap-use-after-free in SortByPTypeProcess. (#6326) 
The process incorrectly deleted original meshes from the scene when cleaning up after an error if those meshes had been added to its output list (outMeshes). The fix ensures proper ownership transfer by nullifying the original mesh pointer in the scene (pScene->mMeshes[i] = nullptr;) when the mesh is moved to outMeshes. This prevents the scene destructor from attempting to delete the mesh again later, while allowing the error cleanup path in SortByPTypeProcess to correctly delete all meshes it owns (both newly created and transferred originals).

36b004e286 Fixed a heap-buffer-overflow in the Half-Life 1 MDL loader. (#6321) 
The loader attempted to read the MDL header without verifying if the input buffer was large enough.
Added a check in MDLImporter::InternReadFile_HL1 to ensure the buffer size is sufficient before proceeding with loading.

6fa9d09a97 AC: Support Double-Sided Faces (#6252) 
* AC: Support Double-Sided Faces

The AC format marks double-sided SURF elements with the 0x20 flag, which Assimp ignored. This commit adds support for double-sided faces.

On encountering a double-sided face via the flag mentioned above, the front face is generated as usual but is then duplicated. The winding order of the duplicate is flipped to form a back face. Vertices are duplicated too so that back faces work correctly with normal vector generation and face smoothing.

* Add test file

* Simplify test case
