The Win32 MessageBox uses the system white-on-gray look that clashes
with the launcher's dark theme (jarring transition every time we
confirm a cancel, show an error, etc.). Replaced with a custom WPF
dialog that:
- Drops in : same Show(message, title, button, icon, default) API as
System.Windows.MessageBox, returns the same MessageBoxResult.
- Looks native to the launcher : dark Brush.Bg.Window background,
Brush.Border outline, Brush.Text.Primary content, AccentButton for
the default action and SecondaryButton for the others.
- Iconography by emoji + colour code : ⛔ red (Error), ⚠ amber (Warning),
❓ neutral (Question), ℹ blue (Information). Mapped from MessageBoxImage.
- Buttons localised via Strings.ActionOk / ActionYes / ActionNo /
ActionCancel — works in fr/en/zh/th/ar like the rest of the UI.
- Owner = currently active window (falls back to MainWindow then
CenterScreen) so it positions correctly even from a child dialog.
- Esc resolves to Cancel/No matching MessageBox semantics.
The 21 MessageBox.Show call sites across MainViewModel, SettingsViewModel,
LicenseDetailsDialog and MainWindow now use ThemedMessageBox.Show with
no signature change — full grep replace + tiny `using` adjustments.
Versions bumped to 0.16.0.
