feat(panettone): Use postgres as the storage backend r/1497

Switch from cl-prevalence to postgres (via postmodern) as the storage
backend for panettone. The first time the application starts up after
this commit, it will (idempotently) initialize the db schema and migrate
over all data from the prevalence snapshot to the database - the plan is
then to get rid of the prevalence classes and dependency once that's
deployed.
