chore(testing): modified paths to account for new changes on the blender side

* added operator to deal with the root path & sub paths in a smarter way
 * various paths are not settable "manually" as pure text anymore
 * overhauled ui for paths
 * overhauled internal handling of paths
 * further refinements to paths handling
 * related fixes & tweaks
 * UI restructure & split out of change detection
 * basic export/assets folder now only available in Ui when blueprints are not in use
 * overhauled bevy integration tests, now done in "two passes" as the external library needs to be exported first
 * cleanups & improvements to the test above
 * started overhauling & massively simplifying the rest of the tests, starting with change_tracking
