test: refresh three suites that drifted from the code they cover

The google ai studio responses test still asserted tools == [], but the
transformation now pops empty tools and tool_choice before calling
completion, so assert the keys are absent.

test_openai_endpoints pinned claude-3-sonnet-20240229, which Bedrock has
retired; move it to us.anthropic.claude-sonnet-4-5-20250929-v1:0.

The AssemblyAI EU passthrough test depended on a credential that no longer
resolves in CI, and the US path plus the bad-key case already cover the
route; drop it rather than keep a permanently red case.
