verbose_name need to have JSONField working with DRF serializers/fields
As an API user I want to be able to list all facilities in Kano by zone, LGA or Ward so that I can see all the facilities in a given area.

/fm/ward/?facility_area__area_id=1
/fm/zone/?facility_area__area_id=2
/fm/lga/?facility_area__area_id=3

/fm/ward/?facility_area__area_name=Test1
/fm/zone/?facility_area__area_name=Test2
/fm/lga/?facility_area__area_name=Test3
 As an admin I want to list contacts by area so that I can create an email or sms list by area.

This needs to be hierarchical so that e.g. contacts for ward-level health facilities are listed when filtering by the LGA they are in
