Hoist startRemoteServer(0) out of per-it() bodies into describe-scope
beforeAll/afterAll for the authentication, dangerouslyOmitAuth,
endpoint-error-paths, and Origin-validation describes — every it() in
these blocks only fires a single request and asserts response shape,
so one shared server per describe is safe.
Storage and additional-coverage describes are unchanged: their tests
mutate per-test filesystem state at common paths or use
heterogeneous server options, so sharing would require reorganizing
the suite (out of scope per the issue).
