fix(presence): leaving Do Not Disturb restores your status instead of "dnd" (#283)
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).

Refs #283

/**
* Status messages are saved per device (`lotus-status-msg-<user>`) and
* re-sent with every presence heartbeat, because a presence write that omits
* `status_msg` clears it on Synapse. #187 DP3: a device never receives its own
* user's presence changes made on other devices, so a status cleared elsewhere
* stayed in its local copy and was re-published on the next heartbeat. The
* heartbeat now reconciles with the server first (see usePresenceUpdater); this
* module only tracks this device's own writes so that a fresh local save isn't
* overridden by a server read that hasn't caught up yet.
