Pull request overview

This PR updates the dashboard’s operational UX for CIRC 0.5 by adding “stale” status indicators (to surface missing telemetry), preventing arm motion commands when the arm isn’t idle, and adding a one-click “Reset All” action for motor error resets.

Changes:

• Add stale-status countdown/indicator to the node status panel.
• Add “Reset All” and stale-status handling to the motor status panel.
• Disable the Arm “Go” action unless a pose is selected and the arm is in an Idle state.

I'm pretty rough at reviewing typescript. I tagged copilot to take a look. Double check the things it came up with. The busy timer is the one that scares me the most.

Looks like it found what I couldn't, which was a way to do them all at once, so I feel better about it now
