Improve Test Generation Dialog Visibility When Already Open

Description

Currently, if a user tries to open the test generation dialog in IntelliJ IDEA while it’s already open but hidden in the window hierarchy, an error message is shown. This results in poor user experience, as the user has to manually locate the hidden dialog.

So instead of showing an error, I suggest to bring the dialog to the front and made visible.

Definition of Done

• When clicked on the "Test Spark" button in the context menu, we should check if the dialog is already open and act respectively.
• If the dialog is not open, we should display it as usual.
• If the dialog is already open, its window should be brought to the top of the window hierarchy and focused.
• No error messages should be displayed when attempting to reopen an existing dialog.
