Subject: [PATCH] fix(permalinks): default permalink for create (#1843)

## Problem

We have quite a number of duplicate permalinks
this does not fix the problem completely, but it does allow for some sort of preventive measure to prevents accidental dups.

we are not sure if of the number of agencies that use dup permalinks for the sake of playground, and it would be hard to enforce this until we have the functionality for playground out. more context [here](https://opengovproducts.slack.com/archives/CK68JNFHR/p1710317487152189)


## Solution

sane default when creating a page.
