All copper chests' inner textures are incorrectly mirrored

Steps to Reproduce:

1. Enable the “Drop 3 2025” experiment

2. Place down any copper chest variant (including double chests)

3. Open the chest or wait for a copper golem to open it for you

Observed Results:
The inner top texture has a groove at the back instead of in the front.

Expected Results:
The inner top texture has a groove in the front, matching the front texture.
