test: fix platform-specific CI test failures

- Fix test_decrypt_linux_not_implemented_error_caught on macOS by mocking is_macos
- Fix test_decrypt_windows_not_implemented_error_caught similarly
- Fix test_get_token_from_config_dir_expands_tilde on Windows by using os.path.expanduser
- Fix test_test_provider_configuration_with_ollama by patching correct import path (graphiti_providers)

Fixes failures on:
- macOS: test_decrypt_linux_not_implemented_error_caught
- Windows: test_get_token_from_config_dir_expands_tilde
- Linux: test_test_provider_configuration_with_ollama
