docs(sso): expose SSO module in the generated SDK reference

Remove @internal from the SsoModule interface and SsoAccessTokenResponse
so the SSO module (getAccessToken and getIdToken) is included when the SDK
reference docs are generated. The JSDoc was already complete but hidden, so
neither method appeared on the reference site. Also add a leading comment to
the getIdToken example so the generator renders the import inside the code
block instead of hoisting it into the code-group title.
