Migration to fill in missing but legit AppDataHashes (#2357)

# Description
We want to start forbidding orders with unknown app data hashes. Before
we can do this, we want to make sure we have defaults set for most valid
orderflow (to not break integrations).

This PR adds a migration for the missing hashes that were observed in
the past week.

# Changes
- [x] Add migration with missing app data hashes

## How to test
Ran migrations locally
