Small fixes and a clearer Last Online column

A small update to keep things running smoothly, with a clearer upload warning for vaults that contain several movie collections and a more accurate Last Online column.

Improvements 🔨

• Introduced a third warning type during package upload to better flag AVaults containing multiple movie collections.
• Updated User List: “Last Logged In” is now “Last Online”, using improved logic to more accurately track when a User last interacted with the Amplify platform within that particular organisation.

Bug Fixes 🐞

• Fixed an issue where clicking a fully uploaded file name in the upload modal didn’t navigate to the file.
• Resolved a problem in the timeline where tabbing between selected clips required two presses instead of one.
• Fixed timeline ruler clicks (when zoomed in) not updating the visible section correctly.
