feat(web/panettone): Add a system for database migrations r/7826
Add a system for writing, running, and tracking database
migrations (changes to the database schema) over time, inspired by but
significantly simpler than postmodern-passenger-pigeon.

Migrations can be generated by
running (PANETTONE.MODEL:GENERATE-MIGRATION "name"), and are numerically
ordered lisp files that define (at least) a function called UP, which
runs the migration. The migrations that have been run against the
database are tracked in the `migrations` table, and when the
`(PANETTONE.MODEL:MIGRATE)` function is called (as it is on startup),
all migrations that have not yet been run are run within a transaction.

This includes one migration `1-init-schema.lisp`, which migrates the
database (idempotently) to the current state of the schema.
