Custom icons, improved GPS, history layout, address fixes

- Replace placeholder SVG icons with custom PNG icons (80x80 padded)
- AffineTransform for pixel-perfect icon centering in menu ring
- Colored circles behind icons with icon drawn at 60% size
- GPS: always wait full timeout (30s), keep best quality fix
- History: show address, PLZ+city, coordinates on separate lines
- Geocoding: fall back to "name" field for street-level results,
  include PLZ+city in cached address data
- Address distance threshold raised to 70m
