Claude f63636f8f4 Add metrics, protected headers and pgpkeys actuator endpoint ...

- metrics (optional Micrometer): per-recipient outcome/policy/reason counter,
  refused counter, key lookup timer below the cache, cache size gauge
- SendReport.RecipientOutcome gains a structured PlaintextReason
- protected headers (RFC 9788, mail.pgp.protected-headers, off by default):
  real headers inside the encrypted part, outer Subject "[...]"
- encrypting keeps the caller's Message-ID
- pgpkeys endpoint (optional Actuator): inspect policy, lookup and key
  validity per address; evict one or all cached lookups
- KeyDiscoveryCustomizer and SecureMailSenderCustomizer extension points
