feat(M51): add SCEP server (RFC 8894) for MDM and network device enrollment

Implements Simple Certificate Enrollment Protocol with single-endpoint
operation-based dispatch (GetCACaps, GetCACert, PKIOperation), PKCS#7
SignedData CSR extraction with fallback for raw/base64 CSR, challenge
password authentication via CSR attributes, and shared internal/pkcs7
package extracted from EST handler to eliminate code duplication.

24 new tests (11 service + 13 handler) plus 5 shared pkcs7 package tests.
