[PUI] URL fixes (#5989)

* added helper to render an instance for an url

* removed unneeded declaration

* restructed PUI urls to improve behaviour:
- removes dead routes
- adds percausion to make sure asset-matching path is always the same
- makes sure subpaths of the PUI path also match to PUI (fixing a current bug with fully reload PUI)

* clean up diff
