add update scope options for location editing

- Added radio button group to LocationEditForm with three update modes:
  1. Current month only (default) - updates specific location
  2. Current and all future months - updates current and subsequent months
  3. All months - updates all locations with same name across all time periods
- Enhanced updateOrAddLocation action with smart update logic based on scope
- Uses name-based matching to find related locations across months
- Added compact radio button styling with reduced spacing and indentation
- Added translations for update scope options in Croatian and English
- Maintains backward compatibility with existing single-location updates
