feat(macos): add Swift 6 strict concurrency compatibility

Prepares the macOS app for Swift 6 strict concurrency mode by:

1. Adding Sendable conformance to WizardNextResult, WizardStartResult,
   and WizardStatusResult in GatewayModels.swift

2. Adding AnyCodable bridging helpers in OnboardingWizard.swift to
   handle type conflicts between ClawdisProtocol and local module

3. Making CLLocationManagerDelegate methods nonisolated in:
   - MacNodeLocationService.swift
   - PermissionManager.swift (LocationPermissionRequester)

   Using Task { @MainActor in } pattern to safely access MainActor
   state from nonisolated protocol requirements.

These changes are forward-compatible and don't affect behavior on
current Swift versions.
