[messaging] encryption of Signal notification messages

[Nick Badger]

+1 to Tony and Felix. From my perspective this is pretty cut and dry. You
have no control over your conversation partner's tech configuration. If
they choose to display your name and the content of the message in lock
screen notifications, then that's their decision and there's nothing you
can (or should be able to) do to change that. If you're worried about that
being incriminating, and you don't trust them to avoid such plaintext
notifications, then you've just implied you don't trust their opsec enough
to communicate with them at all.

Also as a reminder, Signal uses an open protocol. I could write my own
client that publishes every message I receive onto my personal webpage.
Either you trust someone enough to talk to them, or you don't!
