Shautvast 2ef6a0fd24 Add SMTP server (step 7) with PGP/MIME external send
Implements a minimal ESMTP listener (AUTH LOGIN/PLAIN, MAIL FROM, RCPT TO,
DATA, QUIT) that sends via the ProtonMail v4 API (create draft → send).

- ProtonMail internal recipients: Type 1 (encrypt to recipient's ECDH key)
- External recipients: Type 32 PGP/MIME — detached signature in a separate
  application/pgp-signature MIME part so the body arrives clean in Gmail.
  The MIME entity is wrapped in an OpenPGP-signed message (Signature=1) to
  satisfy ProtonMail's mandatory signature check on all external sends.
