fix(profile): private notes say they are stored unencrypted on the homeserver (#329)

"Notes only visible to you" overstated it: notes live in plain account
data that homeserver admins can read. Say so under the note box (and
link it as the box's description): "Only you can see this in Lotus Chat.
It's stored on your homeserver and isn't end-to-end encrypted."

Fixes #329
