devices/<serial>/log messages now carry a "type": "log" or "status".
"log" persists a LocatePoint as before; "status" carries the same
position + telemetry shape but is broadcast live over the job's
realtime channel without touching locate_points — it's a current-
position update, not a recorded point.
The job map renders the latest status as a blue "you are here" marker
(with a soft accuracy-radius halo) that moves in place as new updates
arrive, separate from the colored polyline of logged points. Clicking
it shows the same detail readout as a logged point.
The simulator gained a message-type toggle (Log point / Status
update) so both paths can be exercised from /sim.

Adds devices/<serial>/log as a job-anchored MQTT ingest path: a locator
identifies itself by serial in the topic (auto-registered on first
sight, org resolved from the job in the payload) rather than by a
pre-provisioned broker credential. Device.serialNumber is now globally
unique so the bare topic segment is enough to resolve identity.
Locator lookup/auto-register logic is shared (LocatorRegistryService)
between this and the existing devices/<mqttUsername>/points path.
New /sim page (own header, outside the main app nav) simulates a
transmitter: pick an open job or create one, set a serial number and
telemetry defaults, and send points one at a time or on an interval
along a simulated walking path. It calls a new authenticated backend
endpoint (POST /orgs/:orgId/sim/publish) that publishes onto the real
broker rather than writing the DB directly, so the simulator exercises
the actual ingest pipeline end-to-end.
