[5/6] Add Python goal control integration coverage

[aibrahim-oai]

Why

Steering and interruption must continue to target the active physical turn while callers observe one stable logical goal handle.

What

Add real app-server integration coverage for:

• steering an active continuation
• steering with stale routed state during rollover
• interrupting active and stale continuations
• stable logical IDs on control responses and results
• equivalent sync and async behavior

This is a test-only PR. It does not change production code, generated types, or generation scripts.

Test plan

• online CI, including the Python SDK suite
• all cases use a real app-server process and deterministic Responses test server; no SDK mocking

Define the SSE gate helper before using it

In this commit, SseGate is imported from app_server_harness, but that module does not define or export it, and its enqueue_sse method also has no gate parameter. As a result, pytest fails during collection of this new test file with an import error before any SDK tests can run.
