fix: resolve CI test failures with comprehensive import and environment fixes

- Fix dynamic import issues in _get_fallback_embeddings function
- Replace fragile dynamic imports with direct imports
- Fix module reload issues by ensuring parent module is loaded
- Add automatic API key environment setup for all tests
- Update test patterns to avoid fragile module reloading
- Fix syntax errors and linting issues
- Resolves KeyError: 'contextforge_memory' and ImportError issues
- Resolves RuntimeError: API key environment variable issues

All 29 test failures should now be resolved.
