Daniel Han-Chen e30c5ed386 Fix/adjust diffusion: backend public_load_pending parity for PR #5754
Round 38 P1: R35e added the public_load_pending() check to the
route-side _raise_if_helper_advisor_busy, but the backend-side
_raise_if_helper_advisor_busy_for_diffusion (used by direct
DiffusionBackend.load_model callers AND called transitively from
the route via backend.load_model) never got the same parity
check. That left a window where:
  * /api/training/start published the "training" pending marker
    via the route helper
  * a script/test calling DiffusionBackend.load_model() directly
    passed the backend's helper-busy snapshot, never checked
    public_load_pending(), and proceeded to destructive owner
    teardown + GPU allocation while training was still pending.

Add the parity check with a kw-only `excluding` parameter on
public_load_pending so a route-wrapped backend call can ignore
the marker its own route already published (route publishes
"diffusion"; backend publishes the separate "diffusion-backend"
tag). load_model gains ignore_public_load_pending_workload to
thread the route's tag through; the diffusion route passes
"diffusion" so the backend's atomic check does not self-block
on the route's own publication.

Verified by smoke test: route-wrapped backend with excluding=
"diffusion" allowed during route's diffusion pending; direct
backend call refused with RuntimeError "Another GPU workload is
mid-handoff" when training is pending. 86 backend tests pass.
