fix(tests): structural path matching for interactions compliance; xfail schema tests

Browse source 
The Google Interactions compliance suite fetches the live spec from
ai.google.dev, which recently restructured:

- the id placeholder is now named {interactionsId}, but the endpoint
  existence matchers looked for the literal "{id}" and never matched,
  even though LiteLLM implements GET and DELETE
  /interactions/{interaction_id}. Match paths structurally (segment
  shape + method) instead of by placeholder name.
- CreateModelInteractionParams was removed; the POST /interactions
  request body is now an AgentInteraction | ModelInteraction oneOf.
  The two schema-compliance tests still assert the old component, so
  mark them xfail (non-strict) with that reason until the suite is
  redesigned against the new component layout.

With this, the interactions compliance suite runs green against the
live spec again (11 passed, 2 xfailed).
