Copilot summary

This pull request makes improvements to the scan completion logic in both the IP scanner and port scanner view models to ensure UI updates occur in the correct order and with appropriate thread priority. It also updates the IP range detection logic to use a configurable public IP address. The most important changes are grouped below.

UI Threading and Scan Completion Ordering:

• In both IPScannerViewModel.cs and PortScannerViewModel.cs, the ScanComplete event handler now runs on the UI thread with DispatcherPriority.Background to ensure all scan results are added before updating scan state, preventing race conditions and improving UI consistency. [1] [2] [3] [4]
• Added comments to clarify the reasoning for the change in dispatcher priority, referencing issue IP Scanner error message is displayed even when host is up #3285 for context. [1] [2]

IP Range Detection Logic:

• Updated the IP range detection in DetectIPRange() to use GlobalStaticConfiguration.Dashboard_PublicIPv4Address instead of a hardcoded IP address, making the detection logic configurable and more robust.

Minor UI Consistency:

• Minor formatting change in the HostScanned event handler in IPScannerViewModel.cs for improved readability.
