fix: include cancel handler in ServiceLauncherModal

[agatha197]

TL;DR

This pull request introduces a change to the onCancel handling in the ServiceLauncherModal to resolve the issue of the modify service modal popping up when clicking the start service button.

What changed?

In the ServiceListPage, the onRequestClose method is called to set the editingModelService to null and remove the onCancel prop.

In the ServiceLauncherModal, the onCancel behavior has been changed to call onRequestClose when triggered.

How to test?

1. Navigate to the serving page.
2. Click the gear icon in the Control column and close the modal with the close button at the bottom (not the x button).
3. Click Create new service button.
4. The create modal should appear.
