+ * ActiveToolButton - Shows the currently selected tool at the top of the Quick Access Bar
+ * 
+ * When a user selects a tool from the All Tools list, this component displays the tool's
+ * icon and name at the top of the navigation bar. It provides a quick way to see which
+ * tool is currently active and offers a back button to return to the All Tools list.
+ * 
+ * Features:
+ * - Shows tool icon and name when a tool is selected
+ * - Hover to reveal back arrow for returning to All Tools
+ * - Smooth slide-down/slide-up animations
+ * - Only appears for tools that don't have dedicated nav buttons (read, sign, automate)
