Add comprehensive test suites and documentation
- Add complete test coverage for referenzen, rollen, and stichworte apps - Implement 54 new tests covering models, relationships, and business logic - Fix MPTT method names and import issues in test implementations - Create comprehensive test documentation in English and German - All 188 tests now passing across all Django apps Test coverage breakdown: - referenzen: 18 tests (MPTT hierarchy, model validation) - rollen: 18 tests (role models, relationships) - stichworte: 18 tests (keyword models, ordering) - Total: 54 new tests added Documentation: - Test suite.md: Complete English documentation - Test Suite-DE.md: Complete German documentation
