Replace the Phase-10-deferred `bundesland = null` assignment with
bundeslandFromRegion(region) so new ingests are Bundesland-filterable
immediately. Add @@index([bundesland]) for filter performance. New
handwritten migration 20260721140000_tender_bundesland_backfill backfills
the ~1671 pre-existing rows (idempotent UPDATE, only where bundesland IS
NULL AND region IS NOT NULL) — applied locally via
`docker exec tessera-ctl-db-1 psql`, resolved as applied in
_prisma_migrations, and prisma generate re-run.
Verified on the local dev DB: 933/1671 rows now have bundesland set
across all 16 Länder (738 remain NULL where region itself is NULL).

- normalize(raw): eForms-DE XML primary for deadlineAt/estimatedValue/
procedureType (RESEARCH Pattern 3); OCDS primary for ocid/buyerName/
title/cpvCodes/region/plz
- deadlineAt/estimatedValue nullable by mandate (RESEARCH Pattern 4) —
missing data normalizes to null, never thrown or zero
- dedupKey priority: ocid -> sourcePortal:sourceNoticeId fallback
- contentHash = sha256(title+deadlineAt+estimatedValue+status), stable
across repeat calls, changes when the deadline changes (SCHEMA-02 hook)
