Ethanfel ea84ffef7c Fix FlashVSR ghosting: restore 2 front dummy frames matching reference ...

The pipeline's LQ conditioning indexing expects 2 front dummy frames
(copies of first frame) as warmup. Our previous refactoring removed
these, shifting all LQ conditioning by 2 frames and causing severe
ghosting artifacts.

Now matches the 1038lab reference preprocessing exactly:
1. _prepare_video: 2 tail copies + alignment + 2 front dummies + back padding
2. _restore_video_sequence: strip first 2 warmup frames + trim to original count
3. Crop pipeline output to padded_n before restoration
