fix(quality): green release/v3.8.50 unit base-reds (#9985)

8 unit-test base-reds reproducing on the pristine release tip, fixed in-source
(fast-gates PR->release do not run the unit suite, so these accrued silently):
- ServiceSupervisor: spawn-failure now resolves with error status (was throwing);
  health-probe-failure path still rejects. Distinct via spawnFailed flag.
- stream + responseSanitizer: numeric passthrough id preserved as string (was
  regenerated chatcmpl-); finish chunk with empty delta no longer swallowed by
  the emptyChoices guard.
- proxyFetch: genuine (non-abort) proxy transport failures keep the underlying
  reason in the surfaced error.
- auto-combo builtinCatalog: advertised undefined-variant auto/* ids (auto/chat,
  auto/best-chat, auto/pro-chat) materialize instead of throwing 'Unknown'.
- getTranslations en.json: add missing providers.iconUrlInvalid.
- optional-transformers-dependency.test: reconcile to #9962's deliberate
  move of @huggingface/transformers to a regular dep (napi onnxruntime).
