Daniel Han a8f7b3de57 Address review findings on the image-generation PR
Backend:
- Sanitize a blank hf_token to None in begin_load and load_pipeline, so the
  default empty Studio token loads anonymously instead of 401ing as an explicit
  empty credential.
- Free the ACTIVE diffusion engine before LLM training and in the delete-cached
  guard: on a native (sd_cpp) selection the diffusers singleton reports
  unloaded, so training could start against a live sd-cli generation and
  delete-cached could remove a GGUF the native engine is using. Both now go
  through diffusion_engine_router.get_active_diffusion_engine().
- Refuse delete-cached while a background image load is downloading the repo
  (or its companion base): status().loaded is False in that window, but the
  delete would yank blobs from under the in-flight assembly. Both engines
  expose the in-flight ids via a new loading_repo_ids().
- Cap request seeds at 2**53-1: seeds round-trip through JSON gallery recipes,
  where JavaScript rounds larger integers, so a restored recipe generated a
  different image. Random seeds were already masked to this range.
- Add the task field to CachedModelRepo: the handler sets it for cached
  diffusers image repos but response_model silently dropped it, letting
  image-only repos pass the chat picker's task gate.

Frontend:
- Offset sequential run seeds by the batch size: the native engine seeds image
  j of a run at seed+j, so a +1 run offset regenerated the previous run's
  batch-mates.
- Revert the optimistic quant selection when a load fails to start.
- Stop disabling the Images page on chat-only hosts: the native sd.cpp engine
  exists exactly for the no-GPU route.
