Daniel Han-Chen 48740c2664 Fix/adjust diffusion: round 24 P1 batch for PR #5754
P1 #1: ``_gpu_workload_busy_for_helper`` in
``utils/datasets/llm_assist.py`` now also gates on the GGUF chat
backend (llama-server) AND the safetensors chat backend. Round 23
extended it to training + export but missed Chat, so a helper /
advisor GGUF could still race a loaded chat model for VRAM.
Both checks fail closed when status is unverifiable.

P1 #2 / #3 / #4 / #5: re-ordered the route-level GPU-handoff
unloads so the diffusion release runs BEFORE the chat releases.
A wedged diffusion unload used to fire AFTER chat was already
gone, so the user lost both on a single failure. Drop chat last
so an earlier failure preserves it. Applied to
``/training/start`` (training.py), ``/export/load`` (export.py),
``/chat/load`` GGUF branch and ``/chat/load`` safetensors branch
(routes/inference.py).

P1 #7 + P2 #13: ``/delete-finetuned`` body now hardens
``model_path`` and ``gguf_variant`` via the shared
``_validate_logged_identifier`` helper, so control characters
and URL-form HF tokens can no longer log-line-smuggle.

P1 #8 + #10: ``/delete-cached`` body hardens ``repo_id`` and
``variant`` the same way.

P1 #9: ``/download-progress`` ``repo_id`` query parameter is
also hardened; the value flows into log lines deep inside
``_get_repo_size_cached`` on lookup failure.

P1 #11: ``CheckFormatRequest.dataset_name`` and
``AiAssistMappingRequest.{dataset_name, model_name}`` in
``models/datasets.py`` now apply the same control-char +
embedded-HF-token validators, matching every other public
request-body model.

All 115 diffusion + training-validation + cached_gguf + export
+ inference model-validation tests pass locally.

(P1 #6 native-path-lease enforcement for diffusion local paths
and P1 #12 React Compiler frontend lint deferred -- both need
focused design / frontend touchups separate from this batch.)
