Fix blank menu labels in options flow

HA validates that async_step_{step_id} exists for whatever step_id
a menu returns, so async_step_init cannot own the menu directly under
step_id="init" without the frontend treating it as a silent virtual
step (no translation lookup). Added async_step_configure to own the
menu; async_step_init delegates to it immediately.
