Fix Meteor LRPT decoding in Docker and enhance weather satellite UI

Docker fixes:
- Add missing COPY for /usr/local/share/ (pipeline definitions were never
  reaching the runtime image — root cause of silent SatDump failures)
- Add libfftw3-double3 and libfftw3-single3 runtime dependencies
- Handle arm64 vs x86 install path differences (/usr vs /usr/local)
- Split SatDump compile and staging into separate layers for better caching
- Add build-time assertions to catch missing pipelines early

UI enhancements:
- Timezone selector (UTC, Local, Eastern, Central, Mountain, Pacific)
  with localStorage persistence — all time displays update instantly
- Pass analysis bar showing 24h quality breakdown and best upcoming pass
- Enhanced pass cards with cardinal direction (NW→SE), BEST badge
- Console timestamps, log level filters (ALL/SIGNAL/PROG/ERR), COPY/CLR
- Pass count in stats strip
- Demo data mode for UI testing without SDR or live satellite pass
- Meteor M2-4 80k baud fallback pipeline option
