#14: after editing a message the edited text reappeared in the composer as a
draft and re-sent as a new message. The input listener saved a draft while
editing, but saveEdit/cancelEdit cleared only the input value, not the stored
draft — so openConvo restored it. Now editing never writes a draft, and
save/cancel clear it.
#8: a contact's subtitle flapped between "last seen …" and "Offline". A
loadSidebar rebuild replaced the row with the server's lastSeen, which is
sometimes null (the disconnect touchSeen is fire-and-forget and can lag the
presence broadcast). Now the client keeps last-seen sticky (never overwrites a
known value with null) and the server never broadcasts a null last-seen for an
offline user.
