feat(store): set trial_ends_at on tenant create

 ### Added
+- feat(store): CreateTenant defaults trial_ends_at to NOW()+14d for customer kind; demo kind gets status='demo' and no trial end
 - feat(keycloak): M4.3 — internal/keycloak adapter (Admin API: org create + IT_ADMIN invite + execute-actions-email + attribute sync). admin_email on POST /v1/tenants triggers KC provisioning; failures emit keycloak.provision_failed audit but don't roll back. POST /v1/internal/keycloak/claims resolves the current claim bundle for a tenant.
 - feat(api): M4.2 — full REST surface (tenants CRUD + lifecycle, catalog, entitlements, API keys w/ argon2 hashing, audit query). pgx-backed Postgres store; in-memory fallback when DATABASE_URL is empty. OpenAPI 3.1 spec at openapi.yaml with kin-openapi contract test.
 - feat(schema): M4.1 — golang-migrate migrations for tenants + tenant_projects + tenant_products + tenant_idp_config + api_keys + audit_log; cmd/migrate binary; testcontainers round-trip + seed + slug-constraint tests
