Action.Email resolves {fieldName} placeholders in the recipient, sender,
reply-to and body, but FormService passed carbonCopyAddress and
blindCarbonCopyAddress through untouched. A CC configured as "{email}" — the
obvious way to send the submitter a copy — reached the mailer literally, so the
address was invalid and the mail failed to send.
Both now go through replacePlaceholders like every other address, and an empty
string is normalised to null so the mailer is never handed a blank recipient.
