feat(mobile): recorder time machine, detections, Moments, dossiers and instant start

Records every live contact into an IndexedDB ring buffer so scrubbing
back shows real past positions with ghost trails; playback at up to
600x; timeline pips from every layer. Detects circling aircraft and
quake clusters on live data and opens them as Moments. Adds the
illustrative Empire State hero Moment over real NYC footprints,
entity dossiers, search and link graphs, geolocated reactions,
skyNow, and a bundled real-data snapshot for an instant first frame.

Its thumbnail draws the recorded orbit tracks. A single aircraft on its second full orbit is a lesser detection (severity 4.5, `single: true`, for example "Helicopter circling Las Vegas Strip"). `momentOfTheDay()` ignores single orbits.
 - `quake-cluster`: three or more M2.5+ earthquakes within 50 km in 24 h. Archetype `number`, with a magnitude series.
 - `squawk` cards now carry `momentId: 'live-squawk-<icao24>'`.
