Lotus encodes DND as status_msg "dnd". After switching back to Auto, the
heartbeat read the server's status, adopted "dnd" as the user's own and
kept re-sending it, so the custom status was lost and other clients kept
showing "dnd"; the Settings status field showed "dnd" too.
pickHeartbeatStatus (unit-tested) never adopts the "dnd" sentinel and
falls back to the device's real status; Profile neither mirrors it into
the local status nor shows it in the field.
Verified on the local Synapse: "🎮 Gaming" → DND (unavailable/dnd) → Auto
→ online/"🎮 Gaming" (before: online/"dnd").
Still open in #283: while in DND other clients show the literal "dnd";
that needs MSC3026 busy presence on the homeserver (matrix#19).

Status messages are saved per device and re-sent with every presence
heartbeat (a presence write without status_msg clears it on Synapse). A
device never receives its own user's presence changes made on other
devices, so the DP3 fix in db864326 — mirroring remote changes from the
Profile page — could never fire: device B kept a status that device A had
cleared and re-published it on its next state change.
Heartbeats now reconcile with the server first: GET our own presence,
send the server's current status_msg and bring the local copy in line.
Falls back to the local copy when the read fails, when the server shows
us offline (invisible mode clears the status by design), and for 15 s
after this device saved/cleared its own status (a server read that
hasn't caught up yet can't override a fresh save).
Verified with two sessions of the same user against local Synapse:
B sets "dp3 old status" → A clears it → B goes hidden→visible → server
stays "" and B's local copy is removed (before: back to "dp3 old status").
A sets "dp3 new from A" → B heartbeat keeps it and adopts it locally.
