Fix api key apis

[herber]

Note

Medium Risk
Removes the standalone api_keys endpoint/module and shifts reveal/rotate to organization-scoped endpoints, which may break consumers relying on the old entry point. Also changes request shapes/signatures for get_member_consumer and API key models, so downstream type expectations may need updates.

Overview
Fixes the generated Python SDK API-key surface by removing the standalone api_keys endpoint/resources and exposing API key rotate/reveal on the organization-scoped endpoints (dashboard_organizations_api_keys and management_organization_api_keys), including new generated request/response types and exports.

Also makes surface_identifier optional for get_member_consumer across dashboard/management/instance consumer endpoints and their generated body dataclasses, only sending the field when provided.
