* Fix failing test_dtype_alias pipeline tests
Cosmos pipelines keep the safety_checker in float32 and require it to be
passed explicitly on reload, mirroring their test_torch_dtype_dict
overrides. PRX skips dtype-dict/save-load tests because the custom
T5GemmaEncoder is not compatible with transformers v5; do the same for
test_dtype_alias.

Adds a pixel-space variant of PRX that denoises raw RGB directly
(no VAE), conditioned on a Qwen3-VL text encoder:
- PRXTransformer2DModel: new optional config args `bottleneck_size`
(two-layer img_in projection for large patch dims) and
`resolution_embeds` (PRXResolutionEmbedder conditions the timestep
modulation on the latent resolution)
- PRXPipeline: support for subclass-tuned tokenizer max length, light
text cleaning, x-prediction flow matching (x0 -> velocity conversion),
and non-unit initial noise scale
- PRXPixelPipeline: thin subclass wiring the above together
(vae optional/None, vae_scale_factor=1, 1024px default)
- conversion script support for the pixel checkpoint format
- registration in __init__ files + dummy objects, docs autodoc entry,
fast pipeline tests
