Copilot summary

This pull request removes all dependencies on the old LiveCharts.Wpf charting library and migrates the Wi-Fi channel chart tooltip functionality to use LiveChartsCore. It introduces a new, richer tooltip for Wi-Fi channel charts, displaying SSID, RSSI, channel, and bandwidth, and extends the Wi-Fi network model to include channel bandwidth information. Several obsolete files and converters are removed, and new supporting classes are added for the updated charting logic.

Migration to LiveChartsCore and Removal of LiveCharts.Wpf:

All references to LiveCharts.Wpf are removed from project files, and related converters and tooltip implementations (LvlChartsWiFiChannelTooltip.xaml, .cs, and associated converters) are deleted. [1] [2] [3] [4] [5] [6]

Wi-Fi Channel Chart Tooltip Redesign:

A new tooltip control, LiveChartsWiFiChannelTooltip, is added, providing a modern UI for displaying Wi-Fi network details (SSID, RSSI, channel, and bandwidth) using LiveChartsCore. [1] [2]
A new data point class, WiFiChannelPoint, is introduced to represent points on the chart, each associated with a specific Wi-Fi network.

Wi-Fi Model Enhancements:

The WiFiNetworkInfo model is extended to include a ChannelBandwidth property (in MHz), and logic is added to determine the bandwidth using native APIs or heuristics based on radio/PHY kind. [1] [2] [3]
Helper methods in WiFi.cs are made private for encapsulation, and new methods are added for bandwidth estimation. [1] [2] [3]

Localization:

The string "Channel width" is added to the localization resources for use in tooltips and UI. [1] [2]

Other:

Minor using directives and references are updated in the Wi-Fi model files.

Pull request overview

This PR enhances the Wi-Fi channel visualization by adding channel bandwidth (width) support and migrates the Wi-Fi channel charts from the legacy LiveCharts.Wpf stack to LiveChartsCore.SkiaSharpView.WPF (LiveCharts2), including a redesigned tooltip and 6 GHz chart handling.

Changes:

Add channel bandwidth detection (native wlanapi.dll BSS list parsing + heuristic fallback) and surface it in the Wi-Fi model and UI.
Migrate Wi-Fi channel charts to LiveCharts2 with new axes/sections setup, new tooltip control, and 6 GHz split view.
Remove old LiveCharts.Wpf tooltip and related converters/dependencies.
