Improved card ordering process

ConnectWise and Autotask have no way to track ordering of tickets to indicate the order in which they should be worked. So the ordering of cards is one of the things TopLeft has always tracked on its own, separately from the data synced from the PSAs.

The ordering method we used when TopLeft was launched years ago has been effective- but it wasn't perfect. It could fail when multiple tickets were dragged between columns very quickly. And it didn't scale well in environments with tens of thousands of tickets. And it made some backend maintenance operations take a long time.

So we've replaced the original method with a better method that fixes each of those problems.

If you were refraining from quickly dragging multiple tickets in a column or between columns, you can resume doing that. Let us know if you run into any issues. Thanks for using TopLeft!
