🧹 Remove unused _strip_known_texture_extensions

[skurtyyskirts]

🎯 What: Removed the unused _strip_known_texture_extensions static method from texture_processor.py, along with its associated unit tests in tests/test_texture_processor.py. Also fixed the test suite mock exception inheritance for requests in tests/test_remix_api.py to pass tests successfully.
💡 Why: To eliminate dead code and improve code health/maintainability.
✅ Verification: Ran pytest and python3 -m unittest discover tests to ensure the test suite is fully green and no functionality broke.
✨ Result: A cleaner texture_processor.py and test suite without untested or dead code, and standardizing requests mock exceptions.
