Add weather satellite decoder for NOAA APT and Meteor LRPT
New module for receiving and decoding weather satellite images using SatDump CLI. Supports NOAA-15/18/19 (APT) and Meteor-M2-3 (LRPT) with live SDR capture, pass prediction, and image gallery. Backend: - utils/weather_sat.py: SatDump process manager with image watcher - routes/weather_sat.py: API endpoints (start/stop/images/passes/stream) - SSE streaming for real-time capture progress - Pass prediction using existing skyfield + TLE data - SDR device registry integration (prevents conflicts) Frontend: - Sidebar panel with satellite selector and antenna build guide (V-dipole and QFH instructions for 137 MHz reception) - Stats strip with status, frequency, mode, location inputs - Split-panel layout: upcoming passes list + decoded image gallery - Full-size image modal viewer - SSE-driven progress updates during capture Infrastructure: - Dockerfile: Add SatDump build from source (headless CLI mode) with runtime deps (libpng, libtiff, libjemalloc, libvolk2, libnng) - Config: WEATHER_SAT_GAIN, SAMPLE_RATE, MIN_ELEVATION, PREDICTION_HOURS - Nav: Weather Sat entry in Space group (desktop + mobile) https://claude.ai/code/session_01FjLTkyELaqh27U1wEXngFQ
