[https://nvbugs/6428094][chore] Unwaive DeepSeekV3Lite tp2pp2 test

[cascade812]

Dev Engineer Review

• Removed the DeepSeekV3Lite TP2/PP2 BF16 4-GPU skip entry from tests/integration/test_lists/waives.txt.
• The change matches the objective to unwaive the test for NVIDIA bug 6428094.
• The change has no API, performance, or error-handling impact.
• The test-list change is limited to the intended entry.

QA Engineer Review

• Modified tests/integration/test_lists/waives.txt.
• Removed the DeepSeekV3Lite TP2/PP2 BF16 4-GPU entry with mtp_nextn=0, no attention DP, CUDA graphs, overlap scheduling, or Torch compilation.
• No test-db/ or qa/ files were modified.
• Verdict: needs follow-up because CBTS coverage data is unavailable.

Waiver removal only. The test sits in a post_merge block (l0_dgx_h200.yml:112), so the green pre-merge L0 here is not coverage for it — worth a /bot run --extra-stage "DGX_H200-4_GPUs-PyTorch-Post-Merge-1" before merge. Not blocking: nvbugs/6428094 has two independent non-repros on 4xH200 (repair-bot 07-09, engineer 07-31) against a single post-merge occurrence.
