fix: Clean up proximity-related configuration options in config.ini.example

- Removed obsolete proximity calculation settings including `proximity_method`, `path_proximity_fallback`, `max_proximity_range`, and `max_repeater_age_days` to streamline configuration.
- Simplified the configuration file for better clarity and maintainability, focusing on essential parameters for geographic proximity handling.
