[test] refactor: move diffusion tests to test_groups directory

[huvunvidia]

Summary

• Moves test_flux_conversion.py from tests/functional_tests/diffusion/flux/ to tests/functional_tests/test_groups/diffusion/flux/
• Moves test_wan_ckpt_conversion.py from tests/functional_tests/diffusion/wan/ to tests/functional_tests/test_groups/diffusion/wan/ (also renamed to test_wan_conversion.py)
• No content changes — pure file moves to align with the test_groups directory structure

Test plan

• Verify tests are discoverable from their new locations
• Confirm no references to the old paths remain

🤖 Generated with Claude Code

Summary by CodeRabbit

📝 Walkthrough

Walkthrough

Test files are being relocated into a new test_groups subdirectory structure. Launch scripts are updated to reference the new test file paths, and test modules adjust their root path calculations to account for increased directory depth.

Changes

Cohort / File(s)	Summary
Launch Scripts tests/functional_tests/launch_scripts/active/L0_Launch_models_flux.sh, tests/functional_tests/launch_scripts/active/L0_Launch_wan_ckpt_conversion.sh	Updated pytest invocation and TEST_FILE paths to reference tests relocated to test_groups/diffusion/ subdirectory structure.
Test Modules tests/functional_tests/test_groups/diffusion/flux/test_flux_conversion.py, tests/functional_tests/test_groups/diffusion/wan/test_wan_conversion.py	Adjusted REPO_ROOT path calculations to use six parent directory traversals instead of five to account for increased nesting depth.

⚠️ Potential issue | 🔴 Critical

Fix broken WAN test target path after file rename.

Line 20 still targets test_wan_ckpt_conversion.py, but the moved file is test_wan_conversion.py. This will cause pytest file-not-found failures.

🔧 Proposed fix

-TEST_FILE="tests/functional_tests/test_groups/diffusion/wan/test_wan_ckpt_conversion.py"
+TEST_FILE="tests/functional_tests/test_groups/diffusion/wan/test_wan_conversion.py"

📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
