feat(winui3): ThemeManager service + Settings drawer + Help/About/Onboarding Builds out the secondary surfaces of the redesigned WinUI 3 host. ThemeManager (Services/ThemeManager.cs) Single-source-of-truth for the active theme. Holds the user preference (System / Dark / Light), resolves it to ElementTheme at request, and raises a Themed event when it changes so the MainWindow can push the AppWindow title-bar button colors. Uses Windows.UI.ViewManagement UISettings to follow the OS app-mode when preference is System. Persistence to UIPreferences lands in the engine-wiring commit. MainWindow theme wiring Replaces the per-handler theme toggle with a ThemeManager subscription: click the title-bar sun/moon -> Toggle() -> Themed event -> ApplyResolvedTheme on the visual tree + the title-bar buttons. Glyph cue: sun = "current is Light, click to Dark"; moon = "current is Dark, click to Light." Initial state applied at construction so the first frame matches the preference. SettingsDrawer (Views/SettingsDrawer.xaml + .cs) UserControl that slides in from the right over the participants table. 56px header, NavigationView with five tabs (Appearance, Routing, Display, Control, Advanced), footer with Reset-to-defaults + Apply/Close. Appearance tab has the theme tri-state picker (System / Dark / Light radio group) and an "Accent peek" row showing the four brand accents (cyan / coral / live / warn) as swatches so the operator can verify Wild Dragon brand is respected on a light desk. CloseRequested event signals the host to collapse the drawer. HelpDialog (Views/HelpDialog.xaml + .cs) ContentDialog with the keyboard shortcut cheat sheet, grouped by category (Global / Participants / Look / Control surface). 540px max height with scroll, mono-spaced shortcut labels at left, body text at right. Replaces the WPF host's HelpWindow at parity. AboutDialog (Views/AboutDialog.xaml + .cs) ContentDialog with the Wild Dragon mark, version + host + engine + brand info as label/value rows, and three quick action buttons (open logs folder, open recordings, check for updates). Mirrors the WPF host's AboutWindow. OnboardingDialog (Views/OnboardingDialog.xaml + .cs) Three numbered steps (Install NDI Runtime / Enable Teams NDI / Pick transcoder topology), no carousel, operator-tone copy ("Don't show this again" defaults checked). PrimaryButtonText "Get started", SecondaryButtonText "Skip" so the dialog is skippable from the first frame as the PRODUCT.md anti-references demand. Build clean: dotnet build TeamsISO.App.WinUI -c Debug -> 0 / 0. Next: wire the drawer's CloseRequested into MainWindow (so the settings icon actually opens / collapses the drawer), then attack the runtime activation blocker (Phase 3 of the migration plan).
