Prevent HomeView from reopening when already presented via deeplink

[Copilot]

Summary

When the homeassistant://experimental-dashboard deeplink is triggered while HomeView is already displayed, it unnecessarily dismisses and re-presents the view. This adds a check to skip re-presentation if HomeView is already on screen.

Changes:

• Added homeView tag to WebViewControllerOverlayedViewTags enum
• Check overlayedController?.view.tag before presenting in IncomingURLHandler
• Set tag on HomeView instance at creation

Follows existing pattern used for settingsView and noActiveURLError.
