feat: 1082 fetch area of use spzs from oracle

[craigyu]

Description

Closes #1082

A simple endpoint to fetch a list of seed plan zone for tested parent trees.

Since Oracle is here to stay for a long time, there isn't a reason for us to have an endpoint on postgres as well to get data from oracle-api.
