test(python): record final admitted-input notification order

Refresh advanced and restart expectations through the final native packaged runtime. Synchronous request finalization places deferred fallback-title events after header/context in parent and child logs; expected SDK notifications must reflect that actual lifecycle instead of forcing the old incidental scheduling order.

Validation: the advanced mismatch was reproduced against the built macOS ARM64 executable, both owning scenarios refreshed, then the complete keyless --scenario all passed, including the new in-history prompt evidence and independent shell/file effects. No SDK runtime or normalizer behavior changes in this commit.
