fix: abort upload behavior to properly handle server-side deletion and frontend state reset (#3114)

* Fixed an issue where aborting an upload would not delete the partial upload from the server. Also fixed an issue where the abortAll function wasn't resetting and reloading the frontend properly

* Add server-side tus delete handler
