return larger data sets on API calls

There are two API changes that would improve our internal reporting workflow. When you get a chance, can you find out if these changes are feasible, and (if so) what effort would be required?

1. increase the items returned per page from 200 to 500

   1. Update All endpoints to increase number of results per page

2. On the student GET, can there be a fourth option to return 'all'

   1. New All students API endpoint or update to existing students endpoint provide an option to return all students across all schools, paginated at 500 results per page (aligned with first request)
