* center the title on full screen modals.
Adding the `[dir=“ltr”]` atttribute to the css rule for a child style didn’t work the way I expected.
`[dir="ltr"] .full-screen .header-item-title` did not match the fullscreen title element, so the style wasn’t applied.
`.full-screen [dir="ltr"] .header-item-title` did match.
* fix the filter to reverse the icon and ‘x’ in the filter input
* more space after the library back icon

In addtion to changing the UI color for “mini cards” from motion blue to extensions aqua, this commit also updates the color variable previously known as ‘$pen-primary’ to ‘$extensions-primary’.

Add more UI states (e.g. differentiating between no access, permission granted but video not loaded, video loaded). CSS cleanup.
