## Summary
Migrates `ConnectionSettingsViewController` from UIKit+Eureka to SwiftUI
with proper business logic separation. The new implementation follows
established patterns in the codebase (`ClientEventsLogView`/`ViewModel`)
while preserving all existing functionality.
**Changes:**
- **ConnectionSettingsViewModel** - Extracted business logic: server
observation, state management, user actions (share/activate/delete).
Fixed NotificationCenter observer memory leak by properly storing and
removing observer token in deinit.
- **ConnectionSettingsView** - SwiftUI replacement with sections for
Status, Details, Privacy, and Actions. Uses `SFSafeSymbols` for
type-safe SF Symbol references. Includes convenience
`embedInHostingController()` extension for cleaner UIKit integration
syntax. Added error alert to display deletion failures to users.
- **SettingsViewController** - Updated to instantiate SwiftUI view via
`embeddedInHostingController()`
- **ConnectionURLViewController** - Added convenience initializer with
optional `row` parameter for SwiftUI navigation compatibility
The old `ConnectionSettingsViewController.swift` remains but is
unreferenced.

N/A - Functional equivalence maintained

## Any other notes
All features preserved: connection status display, URL configuration,
privacy settings, server management (activate/share/delete). The
ViewModel uses `@MainActor` with proper lifecycle management and
reactive `@Published` properties. Code follows project conventions
including SFSafeSymbols usage and proper memory management.
Error handling improved: deletion failures are now displayed to users in
an alert with the error's localized description, providing better user
feedback compared to the original implementation which silently
suppressed errors with `.cauterize()`.

## Summary
Converted `ConnectionURLViewController` from UIKit/Eureka forms to
native SwiftUI (`ConnectionURLView`) with snapshot test coverage.
**Changes:**
- **ConnectionURLView.swift** (new): SwiftUI implementation with
Form-based UI
- URL input with validation (internal/external/cloud toggle)
- Dynamic SSID/hardware address lists with add/delete
- Location permission checks (iOS 14+ accuracy support)
- Local push configuration with doc link
- Promise-based save with error handling
- **ConnectionSettingsViewController.swift**: Push SwiftUI view via
`UIHostingController` instead of `ButtonRowWithPresent`
- **ConnectionURLView.test.swift** (new): Snapshot tests for
internal/external URL types in light/dark modes
- **ConnectionURLViewController.swift**: Removed (393 lines)
Net: -2 lines, modernized architecture, improved maintainability.
