feat(webserver): OpenAPI spec improvement

Previously, PagedResult contains ArrayListTotal which is a list with a total in it. But due to that, ArrayListTotal is not recognized as an array for the OpenAPI spec so all the endpoints that use it generates incorrect specification.
Switching to a list fixes the issue.
The serialized form is not impacted.
