The proxy's ingress hardening (commit 842eea0131) now strips client-supplied
`mock_response` from the request body unless the calling key or team has the
`allow_client_mock_response: true` admin-metadata flag set. The e2e model
access tests rely on `mock_response` to short-circuit the LLM call, so without
the flag they hit real backends — the bedrock wildcard route fakes out to a
shared example endpoint that now 404s on unsupported paths, causing
`test_model_access_patterns[key_models2-bedrock/anthropic.claude-3-True]`
(and the bedrock/anthropic.* row that pytest -x never reaches) to fail.
Set `allow_client_mock_response: true` on every key and team this test file
provisions so `mock_response` is preserved end-to-end.
