Case Report changes

Integrate with the new ability of CasePaginator to take an arbitrary filter expression for elasticsearch.

Add linked DCTL/FIDA filter, but disable for now until I can test it and we're sure about the fixture structure.

Disable Allocated To filter until there's a calculated case property for that.

Depends on https://github.com/dimagi/core-hq/pull/493

Fixes (Case:50492)
