nsc-events-nestjs_16_608_search_users_api_update (#168)

* users api update (searching/filtering/pagination)

* comment out getAllUsers testing because refactoring broke it

* try again

* fix tests with new search function (getAllUsers)

* refactor query for 3 search inputs

* refactor controller and service to follow best practices

* add sorting (by first name, then role)

* fix pagination bug + tests

* bugfix didn't go through?
