Baked Ambient Occlusion not visible when selecting Mode Occlusion

[ikonnow]

ArmorPaint version:
c832bb8

OS / GPU model:
Windows, NVIDIA GeForce RTX 4080 Laptop GPU, Intel(R) UHD Graphics

Issue description:
After baking Ambient Occlusion (AO) and selecting "Mode Occlusion", the AO texture is not displayed on the mesh. The mesh appears completely white, looking like unlit without any AO shading.

Additionally, there is inconsistent naming in the UI: the bake dropdown uses "AO" while the mode selection uses "Occlusion".

Steps to reproduce:

1. Open ArmorPaint and load a 3D model
2. Go to the Bake panel and select "AO" from the dropdown
3. Bake the Ambient Occlusion
4. After baking is complete, go to Mode and select "Occlusion"
5. Observe that the mesh appears white/unlit without the AO texture visible

This has been causing confusion for years so I decided to move the baking tool into the new Bake Texture material node.

Old workflow - baking result was always stored in the base color of currently selected layer regardless of bake type
New workflow - baking result is stored in the node and can be further processed / used as needed

In the example below I have baked ambient occlusion, connected the result to the material output and created a fill material. Will continue to improve the Bake Texture node.
