Update test configurations and enhance test robustness

- Modified CI workflow to run all tests for the `sd-core` package, improving clarity in test execution.
- Updated test attributes to use multi-threading for better performance in `cloud_credentials` tests.
- Enhanced test setup in `key_manager` to avoid database conflicts by using unique directories for each test run.
- Improved assertions in `hlc` tests to ensure correct timestamp and counter behavior.
- Clarified comments in `registry` tests regarding the circular relationship between location and entry.
- Removed outdated blurhash tests to streamline the test suite.
