Update robot state if time since last command exceeds timeout

[KazuyaOguma18]

Description

When starting both move_group and moveit_servo simultaneously, controlling the arm with move_group first and then performing jog operations with moveit_servo resulted in the jog operations being executed from the arm's initial pose, without considering the results of the previous control.

To address this issue, the robot's state is now updated synchronously, halting other processes if no control commands are received for a duration exceeding the incoming_command_timeout, which indicates that no jog operations are being executed.
