Go to a project Security Reports page, and click on a security hotspot link of a category that would be outside of the security hotspot page first data load due to pagination page size (default page size is 500).
Update the WS api/hotspot/search to support 3 new filter parameters (one for each security standard): sonarsourceSecurity, owaspTop10, sansTop25. Each of these 3 will accept a list of categories available for the security standard. This will be consistent with the behaviour of api/issue/search. Adapt the frontend to display a simplified list in such case (similar to what's done with the permalink).
