Add motion mode support for H1_2

- Add motion_mode parameter to H1_2_ArmController constructor
- Use kTopicLowCommand_Motion publisher when motion_mode is enabled
- Add motion control logic in motor state control loop
- Add gradual weight transition during homing sequence for motion mode
- Update main teleop script to pass motion mode flag to H1_2_ArmController
