feat: Add GPX import/export functionality and enhance trail management

Browse Source 
- Implemented GPX export and import features in GpxService for location trails.
- Added UI controls for exporting and importing trails in the TrailControls widget.
- Introduced localization strings for GPX operations in Italian and Slovenian.
- Enhanced MapProvider to manage imported trails and toggle visibility for contact trails.
- Updated trail color management with TrailColorService for consistent color assignment based on contact roles.
- Improved UI for displaying contact trails with toggle options for individual and all contact trails.
- Refactored detailed compass dialog to remove unnecessary path toggle button for contacts.
