ltxv: relax frame_idx divisibility for single frames. (#7146) 
This commit relaxes divisibility constraint for single-frame
conditionings. For single frames, the index can be arbitrary, while
multi-frame conditionings (>= 9 frames) must still be aligned to 8
frames.

fix: ltxv crop guides works with 0 keyframes (#7085) 
This patch fixes a bug in LTXVCropGuides when the latent has no
keyframes. Additionally, the first frame is always added as a keyframe.
