fix(behavior_path_planner): change module initial state to WAITING_APPROVAL

[go-sakayori]

Description

Each initial state of scene module in behavior path planner has been set to RUNNING by the setInitState function: therefore, the state would transfer from IDLE to RUNNING.
From the perspective of state transition, each module should transfer from IDLE to WAITING_APPROVAL.
This PR sets the initial state to WAITING_APPROVAL inside the setInitState.

Since LC is already overriding to transit IDLE -> WAITING_APPROVAL -> RUNNING, this is OK.
