Remove Supabase
The database moved to a container of our own; the platform is gone.
This takes out what was left of it — and, where the leftovers were load
bearing, moves rather than deletes.

Moved, not deleted:

  supabase/migrations/  -> db/migrations/      the schema's source of truth
  supabase/build-org.ts -> scripts/build-org.ts
  lib/supabase/types.ts -> lib/types.ts        52 import sites repointed

The bookkeeping needed care. It lived in `supabase_migrations.schema_migrations`,
and simply renaming the schema would have left the runner facing an empty
table: it would have called all 67 migrations pending and replayed them
against a database that is long since current. So the runner now creates
`migrationen.schema_migrations` and, once, copies the old rows across —
guarded so a second run does nothing and a fresh database skips it entirely.
Only then does migration 20260907100000 drop the old schema.

Deleted: the CLI config, the seed, the historical schema/function dumps
(nothing read them), scripts/umzug-von-supabase.sh (the move is done), and
both Supabase packages plus the CLI. Nothing in the application imported
them — the build now succeeds with no environment variables at all, which
is the proof.

Integration tests: six of them signed in through Supabase Auth and asserted
against the anon key and the service role. That model is gone, so the tests
were not portable — they are deleted. session-context and
employee-status-filter already ran on pg and are untouched; om-reporting is
ported to a direct connection because it guards a real risk (the reporting
line rule exists twice, once in SQL and once in TypeScript).

CI: the integration job started a Supabase stack. It now runs a postgres
service, applies deploy/db-init and every migration to an empty database —
that was the valuable part, and it still holds — then checks that a second
run is a no-op, which is what proves the bookkeeping works.

Docs: security-review.md audited a service-role key, a cookie adapter and
auth.users, none of which exist. Restating findings about removed components
would suggest today's system had been reviewed; it has not. It now records
what was removed and says a fresh review is due. data-model.md was already
marked obsolete and described the pre-OM schema; azure-migration.md was a
plan for a route not taken. Both deleted.

Verified: npm ci, typecheck, lint, 445 tests, build — all clean without the
packages. Integration tests skip cleanly with no database. Migration SQL and
the runner are reviewed but NOT executed: no Docker here, and the old
instance no longer resolves.

-- Die Anwendungsrolle muss die Personalnummern-Sequenz fortschreiben dürfen.

-- Hintergrund: employees.personnel_number ist GENERATED ALWAYS AS IDENTITY.
-- Der Massenimport übernimmt die Nummern aus der Quelldatei — sie stehen auf
-- Lohnzetteln, in Akten und auf Ausweisen, ein Import darf sie nicht neu
-- vergeben — und schreibt danach den Zähler auf das neue Maximum.
--
-- Ohne diesen Schritt vergäbe die Datenbank bei der nächsten Neueinstellung
-- eine Nummer, die der Import bereits verbraucht hat. Der eindeutige Index
-- weist sie ab, und zwar erst Wochen später beim ersten Eintritt nach der
-- Übernahme — weit weg von der Ursache.
--
-- `setval()` verlangt UPDATE auf der Sequenz. `usage, select` reicht nicht;
-- genau daran ist der erste Durchstich gescheitert.
