Always give new files and dirs a new index if their names are taken (#3460)

* Add actual support for makeUnique parameter

* Add uniqueness logic to dirs, make text-to-cad receive unique filename

* No longer need makeUnique flag, it's always on

* fmt

* Don't show toast when name hasn't changed during a rename

* fmt

* Get "interact with many" text-to-cad test passing again

* Get "engine fails export" back to reliably green

* Maybe more stable click target for text-to-cad test

* Make "export is already going" test moderately more reliable

* Mark "export is already going" as fixme

* Undo that fixme thing I take it back
