Subject: [PATCH] test(interactions): validate response fields against
 Interaction schema

Google restructured the live spec at ai.google.dev/static/api/
interactions.openapi.json: the output-only fields (notably the
`steps` array, formerly `outputs`) moved off the request schema
`CreateModelInteractionParams` onto a dedicated `Interaction`
response schema. The response-side tests still read from the
request schema, so `test_interaction_response_fields` failed with
"Output field 'steps' not in spec".

Point `test_interaction_response_fields` and `test_status_enum_values`
at the `Interaction` schema (the semantic response object; all output
fields incl. `steps` present there). Request-side tests keep using
`CreateModelInteractionParams` (all request fields verified still
present). 13/13 pass against the current live spec.
