Adds fastvideo/tests/ssim/test_wan_ti2v_similarity.py covering both workloads the checkpoint serves: text-to-video, and image-to-video when an image is passed. CI-friendly params (45 frames, 4 steps, 480x832 for the text case; the image case derives its size from the image inside the pipeline's fixed pixel budget) with the registered preset defaults behind --ssim-full-quality. Runs on one GPU so the lane's lease broker can pack it next to other one-GPU tasks; the Wan2.1 files' 2-GPU sequence-parallel path is already covered by them. Wires the file into the merge planner's Wan family (and its contract test) so Wan changes select it once this is on main, and fixes the Wan coverage sentence in the SSIM README.
