Add multi-arch build support and detailed antenna guide
Multi-arch Docker builds:
- build-multiarch.sh: Cross-compile amd64+arm64 on x64 and push to
registry, so RPi5 can docker pull instead of building natively
- docker-compose.yml: Add INTERCEPT_IMAGE env var to support pulling
pre-built images from a registry instead of local build
- README.md: Docker build section rewritten with multi-arch workflow,
registry pull instructions, and build script options
Weather satellite antenna guide (sidebar panel):
- V-Dipole: ASCII diagram, 53.4cm element length, 120 degree angle,
materials, orientation, connection instructions
- Turnstile/Crossed Dipole: phasing coax length (37cm RG-58),
reflector distance (52cm below), RHCP explanation
- QFH Quadrifilar Helix: design overview, materials, height (46cm),
hemispherical gain pattern
- Placement & LNA: outdoor requirements, coax loss figures,
LNA mounting position, Nooelec SAWbird+ recommendation, Bias-T
- Quick reference table: wavelength, quarter-wave, elevation,
duration, polarization, APT/LRPT bandwidth
Also added Weather Satellites and ISS SSTV to README features list,
SatDump to acknowledgments.

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)
