feature: show folder description in Home tree view

It would be nice to see the folder description on the Home page when Tree View is enabled:

<img width="500" height="300" alt="Image" src="https://github.com/user-attachments/assets/9759fe78-befe-42c4-8623-50f0aa476dc5" />

Description configured here:

<img width="200" height="200" alt="Image" src="https://github.com/user-attachments/assets/63696e69-7c39-4575-a7b8-34c518198e03" />
