refactor overlay stack and modals to allow multiple and better navigation
overlays will not close previous ones so that they don't conflict and there can essentially be unlimited modal navigations. Done by passing the modal data to each modal using a global hook instead of relying on local data for each.
When navigating to a new path, it closes all modals.
On CollectionOverlay, when opening a new details modal overlay, it closes the previous using a custom ShowDetails handler.
This isn't the cleanest approach, but offers the greatest flexibility in the future
