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 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
