Moves the seven ContentDialog flows (rename, pen color, sensor parameters,
web-server settings, web-server authentication, save report, about) plus the
save-report file picker out of MainWindow into a DialogService. The service
reads the live XamlRoot through a provider and writes results back through the
view model; MainWindow's menu/context-menu handlers now delegate to it. The
parameter-editor row builder, the IPv4-address helper, and the
ParameterEditorRow record (all used only by these dialogs) moved with them, and
four now-unused usings were dropped.
First code-only step of the XAML migration; pure relocation, behavior
unchanged. Verified by clean build, 199 tests, and an app smoke-run.
