"""Integration test: on_control fires before control()/on_state, with the full ClimateCall.
on_control's lambda argument exposes get_mode()/etc. on the *requested* ClimateCall, while the
entity's own .mode field still reflects the state *before* control() applies the change --
proving the firing order is on_control, then control(), then on_state.
