fix(video): correct pipeline classes for ltx 2.3 i2v and condition variants

Browse Source 
The 2.3 I2V variants (Dev, Distilled, SDNQ-4Bit, Distilled SDNQ-4Bit)
were registered against LTX2Pipeline, whose __call__ does not accept an
image kwarg; init images were silently dropped. Route them through
LTX2ImageToVideoPipeline instead.

Also register the four 2.3 Condition variants under LTX2ConditionPipeline
so the multi-condition (image/video/gallery prefix) generation path is
reachable on LTX 2.3.
