Handle SMTP 550 recipient-rejected errors with structured SmtpSendException

- Add SmtpSendException with smtpCode/smtpResponse/isRecipientRejected()
- smtpSend() $expect closure throws SmtpSendException (with code) instead of RuntimeException
- SmtpRelay::send() re-throws SmtpSendException so callers can inspect it
- request-access.php (new): catch 550 → roll back token+approval, return HTTP 422 with FR user message
- request-access.php (resend): catch 550 → HTTP 422 instead of silently claiming success
- StudentEmail::sendConfirmation(): catch SmtpSendException → log+false (submission not aborted)
- admin/actions/access-request.php: catch SmtpSendException post-approval → flash warning (recipient-rejected vs transient)
