Before, we were relying on just changing the cards_count in account, but this
could create problems where the system to calculate the next card number fails due
to the unique constraint.
To keep as much of this as we can in the `fizzy-saas` gem, this PR
opts to store console/audits models in a separate database, and so:
- the gem contains the migrations and the database config
- the app contains a separate schema file distinctly for SaaS concerns
- Rails' current behavior prevents us from easily keeping this file in the gem
Also note that the stock `audits1984` schema is updated to reference
the auditor via a UUID foreign key.
Finally, in order for the database schema file to be located in the
gem directory (and not the application directory), it's necessary to
monkeypatch `AR::DatabaseTasks.schema_dump_path` to support absolute
paths. This functionality has been proposed upstream in
https://github.com/rails/rails/pull/56290 but is awaiting a decision
from the core team.
