API: add organizer-level orderpositions endpoint (#5848)

* initial implementation

* handle permissions

* split out organizer list endpoint

* remove left over empty lines

* revert import changes

* tidying up

* revert no longer needed test changes

* revert no longer needed test changes

* Apply suggestions from code review

Co-authored-by: Richard Schreiber <schreiber@pretix.eu>

* add event to api response

* prefetch
