## Summary by CodeRabbit
* **Bug Fixes**
* Malformed ACME URLs and resource identifiers now return a clear **400
Bad Request** response instead of a **500 Internal Server Error**.
* Error details were improved to more accurately distinguish malformed
client requests.
* **Tests**
* Added an integration test covering invalid ACME endpoint path IDs
across resource types, verifying **400** responses with the expected
malformed error type.
