settings: Update quota notice text and style.

Changed the text of the quota notice to
"Your organization is using x% of your 5 GB file
storage quota. Upgrade for more space."

Instead of having a link on "Upgrade", the entire
notice is now a clickable banner with a rocket icon,
consistent with other banners used in settings.

Fixes #29077.
