fix(companion): show the sender's own timestamp for synced/queued messages

Browse Source 
DM, room and channel history always stamped a message with receipt time
(rtc_clock.getCurrentTime()), even though the sender's real timestamp was
already available (and, for DMs/rooms, already threaded through to
addDMMsg -- just never used for display). Live-received messages hid this
because receipt lags origination by only seconds, but a room-sync replay or
an offline-queued message held by a repeater can arrive long after it was
sent, so a burst of backlog messages all showed as "just now".

storeDMMsg() now prefers msg_ts (falling back to receipt time only when
unknown). addChannelMsg() gained a timestamp parameter, threaded from
onChannelMessageRecv() down through AbstractUITask/UITask, with the same
fallback. The DM dedup check and outgoing-message timestamps are unaffected
(they use msg_ts directly, already correct).
