fix: resolve typecheck errors in generated code

- Remove `export * from './mfa/interfaces'` in index.ts to fix duplicate
  Factor export clash with user-management/interfaces
- Add serializeDirectoryState() to reverse-map active→linked, inactive→unlinked
- Fix OrganizationMembership interface to not widen required base properties
- Fix user serializer to use undefined instead of null for optional external_id
