Pin spec server path, not full URL, in base-URL drift test

Previously test_default_base_url_matches_spec_servers compared the
full URL of openapi.json's first server entry against DEFAULT_BASE_URL,
which forced the spec to come from the production host. Regenerating
the client from staging (different host, same /v0.4 path) tripped the
test even though the API-version contract was identical.

The version path is the actual safety property the test cares about;
the host is just the environment, and the runtime base URL is
overridable on IonQClient anyway. Compare urlparse(...).path on both
sides so staging regenerations pass while a /v0.4 -> /v0.5 bump still
fails until DEFAULT_BASE_URL is updated.
