fix(management_api): fix organization connections empty properties via spec

Add local OpenAPI spec and fix get_connections_response so connections
array decodes correctly. API returns connection objects directly; spec
had items as connection (wrapper). Use connection_connection schema for
get_connections_response.connections items and connection.connection.

- Add spec/kinde-management-api-spec.yaml (from api-spec.kinde.com)
- Add connection_connection schema; get_connections_response.connections
  items and connection.connection reference it
- Update generate.go to use local spec
- Regenerate management_api (ogen) so GetConnectionsResponse.Connections
  is []ConnectionConnection; no manual oas_* patches
