docs: record what the send side actually has, in item 123

The entry said sending should be an external script on the same model as
mailsync.sh. Measured on the machine, there is no such model to copy: the
fetch side has mbsync and the send side has nothing.

No MTA is installed at all, msmtp and sendmail are both absent, and neomutt
sends over its own built-in SMTP configured per account in
~/.config/neomutt/accounts/*.rc. So the working setup this application
mirrors has no external send path either.

That makes the first question a non-UX one, ahead of everything the note
lists: sending needs either an MTA the user chooses to install and
configure, which is the only shape that keeps the no-network-protocol rule
intact, or a decision to relax that rule. Recorded so the brainstorm does
not assume the tidier answer, since installing and configuring an MTA is
work he has not asked for and the credentials already exist elsewhere.

Also notes that all five accounts already configure a drafts folder, so the
draft half has somewhere to live before anything is decided.
