Request access from Dashboard, version notifications, and UI enhancements

Users can now request access directly from the Dashboard when they try to open a studio or organization they don’t have access to.

When a new version of Dashboard is available, a notification message will be displayed.

• Following our homepage redesign, the Insights section has been updated to better match the new homepage.
• History & Favorites now display image previews for Canvas documents.
• Favorites now update instantly as you add or remove items.
• The organization menu design has been refreshed with an updated UI and quick links to manage the organization and invite new users.

• Fixed an issue where users could see studios within an organization that they didn't have access to.
