Re #9476

Created a layout with empty panels. They will be done in other branches.

webapp/components/annotation/annotationPanel.tsx

+/**
+ * Creates a panel in the annotation screen that contains a list of annotations.
+ * @returns Panel with a list of annotations.
+ */
+function AnnotationPanel() {
+    return (
+        <div>
+            <p>Panel with a list of annotations</p>
+        </div>
+    );
+}
+
+export default AnnotationPanel;
