[Feature request (NT)] - Implement a Proper Stop Mechanism for Interamap

[zangjiucheng]

Feature Description

Describe the feature

Currently, there is no proper way to stop Interamap once it has started. Since it spawns multiple sub-processes (e.g., live-point server, HTTP server, etc.), stopping the UI does not terminate the background processes, which continue running. This can lead to resource consumption issues and potential conflicts when restarting the application.

Expected behavior

• Provide a way to gracefully terminate all running servers and sub-processes with a single action.
• Allow users to stop all processes using a single Ctrl + C command in the terminal.
• Ensure that all sub-processes started by Interamap are properly cleaned up on exit.
• Implement this stop mechanism within the launcher as well, ensuring that all associated services are terminated when the launcher stops Interamap.

Additional context

• Properly test the implementation to ensure that all spawned processes are correctly terminated when Interamap is stopped.
• Consider adding logging to confirm that each sub-process shuts down as expected.
