Refactor and enhance reset_channels_to_idle_state

- Refactor reset_channels_to_idle_state to reset_channels_to_defaults
and enhance functionality with direction reset logic. This is because
some tilt test cases were failing due to modified run limit values in some
of the previous core test cases. See #1089-3.
- A relay channel listener has been added to diagnose channel
states during tests.
