## 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.
