feat(structures): add Region/Delegation/Structure schema + seed (ADR-0027 PR 1)

Schema (Prisma): three new public-schema models per ADR-0027 - Region (INSEE code PK), Delegation (dept code PK + regionCode FK), Structure (portal-internal code PK + kind discriminator + nullable unique finess/siret/codePaie + nullable delegationCode FK). Migration: hand-written, matches the style of init_audit_schema and users_directory. DDL + CHECK constraint on Structure.kind mirroring STRUCTURE_KINDS + indexes + inline seed (Region 75 Nouvelle-Aquitaine, Delegation 33 Gironde, structures 0330800013 + 0330800021 medico-social Bordeaux/Merignac + siege APF national). Seed is the minimum the 19 test-tenant personas reference; ADR-0029's cascade sync supersedes it when it ships. Catalogue (TypeScript): apps/portal-bff/src/structures/structure-kind.ts exports STRUCTURE_KINDS as const + StructureKind type union + isStructureKind type guard. Jest spec covers catalogue content, type guard, narrowing. Drift gate: extended to scan property-literal "kind: 'X'" expressions in files that import from structure-kind.ts. Three-layer defense in depth for Structure.kind = TS type union + Postgres CHECK + CI gate. 22 spec tests passing. No consumer code yet - PrismaScopeResolver that dereferences Structure.code from UserScope.value lives in ADR-0026 PR 2, which depends on this PR landing first. Reviewer heads-up: schema.prisma already has a User model (ADR-0020 user-directory cache); ADR-0026 PR 1 introduces a different User (UUID PK + Person FK). Naming collision flagged for that PR to resolve - not touched here.

+-- Organisational hierarchy (per ADR-0027).

+-- Region → Delegation → Structure. The portal's ADR-0025 scope-axis
+-- dereferences these three layers — the BFF guard
+-- `principalCoversResource` walks etablissement → delegation → region
+-- to decide whether a scope covers a resource. The schema lives in
+-- the public schema; ADR-0029 will populate the full APF inventory
+-- via the cascade sync, additively into the columns defined here.
+--
+-- Inline seed at the bottom of this file: just the codes the
+-- test tenant exercises (Région Nouvelle-Aquitaine, Délégation
+-- Gironde, two médico-social structures + the APF national siège).
+-- Superseded — not extended — by ADR-0029's cascade sync once it
