Daniel Han-Chen e3ce1c818e Fix/adjust diffusion: round 33 P1 batch for PR #5754
Two round-33 reviewer findings: hub-floor consistency and the
multipart upload filename validator gap.

Dependencies: reverted the round-26 huggingface_hub>=1.3.0 floor
in no-torch-runtime.txt and pyproject.toml (round 33 P1 #1-#5,
4/12 vote consensus). studio.txt forces huggingface_hub==0.36.2
to match the transformers==4.57.6 pin in extras-no-deps.txt, so
the 1.3.0 floor was internally inconsistent. Reviewers
reproduced the resolver conflict on a fresh install.

Empirical justification (re-verified on the live B200 host before
the revert): huggingface_hub 0.36.2 + transformers 4.57.6 +
diffusers 0.37.1 imports Flux2KleinPipeline cleanly and runs
end-to-end image generation. transformers 4.57.6 carries its own
transformers.utils.hub.is_offline_mode and does not actually need
huggingface_hub.is_offline_mode at import time. The original bump
was guarding against the (never-realised) transformers 5.x path,
which extras-no-deps explicitly pins away.

Validation: multipart /seed/upload-unstructured-file now applies
the same _no_control_chars and _reject_embedded_hf_token checks
to file.filename that SeedInspectUploadRequest.filename already
applies in the JSON variant (round 33 P1 #7). The filename is
reflected back to the client, persisted in the per-file meta
JSON, and echoed by error responses, so the JSON-side hardening
must not be asymmetric with the multipart path.

Skipped (consistent with prior rounds):
  * Find_spec vs full import (R33 P1 #6): preserves test
    compatibility with the huggingface_hub stub fixture.
  * React hooks set-state-in-effect lint (R33 P1 #8): codebase
    has 146 pre-existing violations of the same rule;
    studio-frontend-ci does not gate on lint.
  * Direct DiffusionBackend.load_model bypass (R33 P1 #9): the
    route is the only production entry point, and the backend
    helper now publishes its own diffusion-backend pending tag
    (round 32 P1 #3). Direct-caller hardening would require
    duplicating the lease check into load_model itself, which
    is out of scope for the route-layer security boundary.
  * One-segment Hub IDs (R33 P2 #10): strict 2-segment Hub id
    check is intentional; one-segment names are not valid Hub
    ids.
  * Cwd-relative shadow of Hub IDs (R33 P2 #11): documented
    side-channel tradeoff accepted in round 31 commit msg.

97 targeted backend tests pass.
