Is your feature request related to a problem? Please describe.
There's no formal link between admin zones and their parents at current in the db, so we need to constuct joins by hand

Describe the solution you'd like
Implement parent_pcod columns in the admin views

Describe alternatives you've considered
Joining on either spatial properties or aspects of the pcod IDs themselves to derive the hierarchy

Additional context
This property is present in the Nepal test data
