chore: Drop setup.sh DATABASE fallback ENV (#2556)
* chore: Remove `DATABASE` fallback ENV

This was introduced without any mention or need, thus removing until a real use-case requires it.

* chore: Remove `USER_DATABASE` fallback ENV

Likewise, nothing requires this to be customizable.

* chore: Consistently use single quote strings
