[Bug] SIGINT interrupt requires explicit shutdown before restart

Bug Description
When I ctrl+c a terminal that's running Pro, then I cannot being Pro back up with a normal run command. I first have to run moveit_pro down before moveit_pro run. I am unable to replicate this 100% of the time, but it does happen often.

This happens on the autowash IPC.

Errors

```moveit_pro run -v --no-browser --no-drivers
Running MoveIt Pro 9.3.1 with robot configuration: autowash_hw_config
Starting services: ['agent_bridge', 'web_ui']

Waiting for MoveIt Pro to start.
