Module error 

Unified error type for Kipuka EST server.

KipukaError covers all failure modes from configuration through certificate issuance. The [IntoResponse] impl produces HTTP responses appropriate for EST clients:

• Client errors return 4xx with a text/plain body describing the problem.
• Server errors return 500 or 503; internal details are logged but not exposed to the client.
• EST-specific error semantics follow RFC 7030 §4.2.3 (CMC response for enrollment failures) and §3.2.4 (HTTP error codes).
