Add weather satellite auto-scheduler, polar plot, ground track map, and rtlamr Docker support

- Fix SDR device stuck claimed on capture failure via on_complete callback
- Improve SatDump output parsing to emit all lines (throttled 2s) for real-time feedback
- Extract shared pass prediction into utils/weather_sat_predict.py with trajectory/ground track support
- Add auto-scheduler (utils/weather_sat_scheduler.py) using threading.Timer for unattended captures
- Add scheduler API endpoints (enable/disable/status/passes/skip) with SSE event notifications
- Add countdown timer (D/H/M/S) with imminent/active glow states
- Add 24h timeline bar with colored pass markers and current-time cursor
- Add canvas polar plot showing az/el trajectory arc with cardinal directions
- Add Leaflet ground track map with satellite path and observer marker
- Restructure to 3-column layout (passes | polar+map | gallery) with responsive stacking
- Add auto-schedule toggle in strip bar and sidebar
- Add rtlamr (Go utility meter decoder) to Dockerfile
