ensureDbCompatibility ran ALTER TABLE / CREATE TABLE IF NOT EXISTS on the
login, register, token and session paths, mirroring columns every
migration under prisma/migrations already creates. The entrypoint applies
those migrations before the server listens and stops the boot when one
fails, so the mirror never had work to do, and DDL on a request path
needs the table's owner: a connection that may only read and write rows
fails every login on it. Drop the module, its call sites and the mocks
that stubbed it out.
Against a real Postgres and the real confirm route: an undated value takes
the report date over the filing date, a value's own date is kept, an
impossible own date counts as none, and a document without a report date
dates the value by its filing date.
