This PR fixes #2769

Implemented changes

• Disable the clicked IDE's Open button while its launch task runs and ignore repeated requests for the same IDE. The button is enabled again when the task finishes, fails, or is cancelled. Other IDE buttons remain available.
• Abort GUI questions that require a choice instead of repeatedly reading an empty answer and flooding the console with Invalid answer warnings. Existing default answers and batch behavior are preserved.
• Add regression tests for prompt handling, duplicate launches, and button states.

Testing instructions

1. Run com.devonfw.ide.gui.AppLauncher from the gui module using Java 25. Set IDE_ROOT to an existing IDEasy root directory.
2. Select a project and workspace.
3. Double-click Open for IntelliJ, Eclipse, or Android Studio. Only the clicked button should be disabled, and only one launch task should start.
4. Check that the other IDE buttons remain enabled.
5. Once the launch task finishes or fails, check that its Open button is enabled again.
