New features:
- NASA GIBS (MODIS Terra) daily satellite imagery with 30-day time slider
- Esri World Imagery high-res satellite layer (sub-meter, zoom 18+)
- KiwiSDR SDR receivers on map with embedded radio tuner
- Sentinel-2 intel card — right-click for recent satellite photo popup
- LOCATE bar — search by coordinates or place name (Nominatim geocoding)
- SATELLITE style preset in bottom bar cycling
- v0.4 changelog modal on first launch
Fixes:
- Satellite imagery renders below data icons (imagery-ceiling anchor)
- Sentinel-2 opens full-res PNG directly (not STAC catalog JSON)
- Light/dark theme: UI stays dark, only map basemap changes
Security:
- Removed test files with hardcoded API keys from tracking
- Removed .git_backup directory from tracking
- Updated .gitignore to exclude test files, dev scripts, cache files
