Split the onboard-controller server/handshake/thin-client work out to
feat/g1_onboard_controller and revert it here:
- unitree_g1.py: drop client + onboard roles, wireless-remote parsing and
motion-service release; restore main's sim/socket-bridge transport. Keep only
the SONIC integration (implicit token action/state, full-body reset/pause,
controller kp/kd + shutdown).
- config: drop onboard/dds_interface/release_motion_control/physical_remote.
- run_g1_server.py + unitree_g1.mdx: reverted to main.
- gr00t/holosoma: keep the move into controllers/ but revert their content to
main (only the package-relative import changes).
