[Backport release/0.0.14] fix(g1): route planner and teleop velocities to the sim connection

[github-actions]

Description

Backport of #4150 to release/0.0.14.

[greptile-apps]

Confidence Score: 5/5

Safe to merge: the added blueprint component completes the expected velocity-command routing to the simulated G1 connection.

What we checked:

• Authored the executable g1-movement-routing-check.py to validate movement-routing behavior.
• Ran the before revision of the script from the repository, and it exited with code 1.
• Ran the after revision of the script from the repository, and it exited with code 0.
• The final output decisively reported nav_cmd_vel, tele_cmd_vel, and cmd_vel states, confirming the observed routing behavior after the revision.

Summary

This change adds MovementManager to the basic G1 simulation blueprint so planner and teleoperation velocity commands share the route to the simulation connection. The checked command-routing composition is complete and no issues were found.
