Daniel Han-Chen 79da5d910d Fix/adjust diffusion: round 27 follow-up P1 batch for PR #5754 
Five additional P1 findings round 27 reviewer flagged on top of the
round 27 commit 6c528fb0 (Counter refcount + handoff visibility were
already covered). Three remaining studio.txt / no-torch-runtime hub
suggestions are NOT applied because they would re-break CI; the
empirical evidence (round 26 commit 65ea3a2c restored CI green) takes
precedence over the reviewer's stale-state suggestion.

1. models/training.py TrainingStartRequest: extend the embedded HF
   token validator to subset, train_split, eval_split. Round 26 only
   added the control-char guard to those three; the token guard was
   asymmetric and would accept owner/data\\nFAKE hf_abcdef...
   payloads through subset / split fields.

2. models/datasets.py CheckFormatRequest: extend both validators
   (control chars + embedded HF token) to subset and train_split.
   Same asymmetric-fix bug as #1.

3. models/data_recipe.py SeedInspectRequest: extend both validators
   to subset and split. Same pattern.

4. utils/datasets/llm_assist.py precache_helper_gguf: register the
   helper repo in the helper/advisor refcount registry around the
   hf_hub_download loop, then unregister in the finally. Without
   this, the FastAPI-startup background pre-cache could be racing
   a concurrent DELETE /api/models/delete-cached against the same
   cache directory. The runtime helper / advisor calls already
   register (round 26 P1 #13/#14) but the precache was the
   asymmetric gap.

5. routes/models.py _loaded_model_matches_deleted_path: match
   bidirectionally (active under target OR target under active) so
   deleting a child directory of a loaded local model (.../my-flux/
   text_encoder while .../my-flux is loaded) trips the guard.
   Mirrors the diffusion delete-guard symmetric path-overlap check.

Tests: 105 targeted (diffusion + cache + inference_validation) and
the broader backend suite pass locally.
