[PM-20348] Add pending auth request endpoint (#5957)

* Feat(pm-20348): 
  * Add migration scripts for Read Pending Auth Requests by UserId stored procedure and new `view` for pending AuthRequest. 
  * View only returns the most recent pending authRequest, or none at all if the most recent is answered.
  * Implement stored procedure in AuthRequestRepository for both Dapper and Entity Framework.
  * Update AuthRequestController to query the new View to get a user's most recent pending auth requests response includes the requesting deviceId.

* Doc: 
  * Move summary xml comments to interface.
  * Added comments for the AuthRequestService.

* Test: 
  * Added testing for AuthRequestsController.
  * Added testing for repositories. 
  * Added integration tests for multiple auth requests but only returning the most recent.
