Marc-André Bombeck b6da360856 refactor(db): drop the runtime schema mirror
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.

/**
* v1.42 (#613) — the day view, its index, the visit preparation, the
* timeline and life events, driven as routes against real Postgres.
*
* What the unit tests cannot show: that each of the three ways this schema
* stores a day lands on the right local day across a clock change, that a
* switched-off module's rows are not in the answer, that a grant scoped to
* some sections reads exactly those sections, that a life event is encrypted
* at rest, audited, and never reaches the model-facing read of the same day.
