Daniel Han-Chen e2f41e4069 Fix/adjust diffusion: round 17 P1+P2 batch for PR #5754
P1: route-layer chat/diffusion/export releases were still
asymmetric. Training start and export load called
``diff_backend.unload_model`` inside a best-effort try/except so a
wedged diffusion backend let the next workload allocate over the
top of the resident pipeline and OOM. Both now use the strict
``_release_diffusion_for`` helper from routes.inference, which
raises HTTPException 503 on status/unload failure or post-check
mismatch.

P2 #9: diffusion load exceptions can include the absolute local
repo / base / gguf path verbatim (FileNotFoundError, OSError from
diffusers / safetensors). The path flows into ``_last_error``,
which ``status()`` returns to every authenticated session. Collapse
the known repo_id / effective_base / gguf_filename paths to their
leaf name before storing the error, mirroring the
``_display_repo_id`` convention used for the public repo label.

P2 #10: when ``repo_id`` is an absolute local path,
``detect_family`` matched _FAMILY_EXCLUDE deny lists against the
full path, so models stored under a parent directory containing
``qwen-image-edit`` or ``3.5`` were misclassified as None. Reduce
the family-detection needle to the leaf directory when the input
looks like a filesystem path; Hub-style ``owner/repo`` ids
continue to use the original needle so existing detection rules
keep working.

P2 #12: ``gguf_filename`` was missing from the
``_reject_embedded_hf_token`` validator. A URL-form quant path
like ``https://hf_xxxxx@huggingface.co/.../flux.gguf`` would be
stored on ``DiffusionBackend._gguf_filename`` and surface in
status() / log lines. Extend the validator to gguf_filename so the
token is dropped before it can leak.

All 85 diffusion-relevant backend tests pass locally.
