Strip unused text_embedding_projection.video_aggregate_embed.* (saves 1.54 GB)

Audio-only inference paths replace this Linear with a zero-returning
dummy after load (see ltx_pipelines.utils.blocks.PromptEncoder
with audio_only=True), so the weights are dead on disk. Removing
them brings audio-components from 6.71 GB -> 5.17 GB; behavior
verified bit-identical via local A/B inference.
