fix: make the z-index of file opener over the reporter

[elevatebart]

When selecting the preferred editor for opening files in CT, we get the reporter above the dialog.

Using this PR we get the dialog over the command log panel.

• Closes CT-421

User facing changelog

Fixed a z-index issue with "Open in IDE" modal in the Component Test Runner.

How has the user experience changed?
