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.
