fix(macos): remove authorizedWhenInUse references (iOS-only API) (#165)

CLAuthorizationStatus.authorizedWhenInUse only exists on iOS. On macOS,
location services only support .authorizedAlways. This was causing
compilation warnings and potentially incorrect behavior.

Fixes:
- GeneralSettings.swift: Remove authorizedWhenInUse check
- PermissionManager.swift: Update ensureLocation and status methods
- MacNodeRuntime.swift: Update location permission check
