Implement Pro Upgrade Notification for Share Analytics

Commit notes

- Added a conditional display for users without a Pro subscription, informing them that detailed share analytics requires a Pro upgrade. - Introduced new UI elements including a notification section with upgrade benefits and a call-to-action button linking to the subscription settings. - Integrated derived state management to handle subscription status and error messages related to Pro requirements.

This enhances user experience by clearly communicating the benefits of upgrading to Pro for accessing advanced analytics features.
