Add Slovenian localization for trail management and device configuration

- Updated `app_localizations_sl.dart` with new strings for trail management, device information, and error messages.
- Enhanced `app_sl.arb` with corresponding translations for the new strings.
- Refactored `device_config_screen.dart` to utilize localized strings for device information and error handling.
- Modified `map_tab.dart` to remove unused trail stats overlay.
- Improved `ble_response_handler.dart` to include additional debug information for parsed contacts and advertisements.
- Updated `trail_controls.dart` to use localized strings for trail management UI, including trail visibility toggle and confirmation dialogs.
