Make Applications extend LiskDAO

Summary:
Ref T11476. This is a bit hacky, but makes `Application` extend `LiskDAO` so we can apply transactions to it with an `Editor` class.

Also fixes schema stuff so builds should produce a clean bill of health again.

This might only get you slightly further, yell if you run into more trouble.

Test Plan:
- Ran `bin/storage upgrade -f` and got no warnings.
- Browsed around, nothing exploded?
