feat(bluemap): Add colored markers based on shop state (#2179)

- Added colored circle SVG markers as new default option
- Green (#2ecc71) for selling shops
- Blue (#3498db) for buying shops
- Gray (#888888) for frozen/disabled shops
- Colors are configurable in config.yml
- Added use-custom-icon option to switch between custom icon and colored markers
- Kept icon-file-location for backwards compatibility
- Adjusted marker Y position for better visibility
