scripts: Add cryptographic verification to authenticode transplant

Add full cryptographic verification of PKCS#7 Authenticode signatures
in authenticode_transplant.py. This includes:

- Extract and verify PE hash from SpcIndirectDataContent against the
  computed Authenticode hash using the signature's own hash algorithm
- Cryptographically verify signer signatures (RSA PKCS1v15 and ECDSA)
  against authenticated attributes
- Extract and display X.509 certificate details (subject, issuer,
  serial, validity) during verify and combine operations
- Refactor calculate_authenticode_hash to compute_authenticode_hash
  supporting multiple hash algorithms (SHA1, SHA256, SHA384, SHA512)
- Add cryptography==43.0.0 dependency and update pyasn1 to 0.6.2
