Migrate SettingsViewController to SwiftUI with NavigationSplitView on macOS (#3968)
## Summary

Migrates SettingsViewController from UIKit/Eureka to SwiftUI. macOS uses
NavigationSplitView (sidebar + detail), iOS uses NavigationStack with
list navigation.

**Changes:**
- **SettingsView.swift** (new): SwiftUI implementation with
platform-specific navigation
- macOS: Sidebar with setting categories, NavigationStack in detail pane
  - iOS: List-based navigation with NavigationStack
- Platform filtering: macOS hides gestures, watch, CarPlay, NFC, help,
whatsNew
- Supports `contentSections` parameter for filtering displayed sections
(defaults to `.all`)
- ServersObserver for real-time server updates via ServerObserver
protocol
- Wrapper views embed UIKit controllers not yet migrated (location,
notifications, NFC, complications, actions)

- **SettingsItem.swift**: Enhanced with `visibleCases(for:)` method to
filter items based on contentSections parameter

- **SettingsSceneDelegate.swift**: Simplified from 189→36 lines
  - Returns SwiftUI SettingsView for all platforms
  - Removed UINavigationController management, NSToolbar delegate

- **WebViewController.swift**, **WebViewExternalMessageHandler.swift**,
**ConnectionSecurityLevelBlockView.swift**: Updated to present SwiftUI
SettingsView

- **SettingsViewController.swift**: Deleted (253 lines removed) - all
functionality migrated to SwiftUI

Example usage with content filtering:
```swift
// Show all sections (default)
SettingsView()

// Show only servers section
SettingsView(contentSections: .servers)
```

Example navigation on macOS:
```swift
NavigationSplitView {
    List(selection: $selectedItem) {
        ForEach(SettingsItem.visibleCases(for: contentSections)) { item in
            NavigationLink(value: item) {
                Label(item.title) { item.icon }
            }
        }
    }
} detail: {
    NavigationStack {
        if let selectedItem {
            selectedItem.destinationView
        }
    }
}
```

## Any other notes
Complete migration from UIKit/Eureka to SwiftUI with full feature parity
including contentSections support. UIKit controllers
(SettingsDetailViewController, NotificationSettingsViewController, etc.)
remain embedded via `embed()` function until individually migrated.

> Migrate SettingsViewController to SwiftUI, on macOS it should be a
split view (sidebar + content). If needed to embed UIKit controllers in
the middle use "embed(<UIViewController>)"
