fix(mobile): polish round: night close-ups, bundled real recording, demo runbook

- Close-ups stay readable at any hour: night-side imagery is graded
  instead of black, and a watchdog drops to flat terrain when the
  keyless terrain host stalls.
- A bundled real ADS-B recording (23 Oct 2026, 08:25-11:06Z; NYC,
  London, Gulf) gives the time machine ghosts to replay on first open.
- Director beats frame their subjects (hearts rise over Midtown), fire
  a deterministic alert, and run in any order.
- Dossiers name operators from airline prefixes and show the privacy
  notice only for real privacy flags.
- The iPad Moment pane carries the record and chat; time machine
  labels no longer collide; demo data ships in the production build.
- mobile/DEMO.md explains how to run and present the demo.
