Windows uses application.Options.Name as the toast AppUserModelID and as
the registry path the Wails notifier reads/writes its CustomActivator
under (HKCU\Software\Classes\AppUserModelId\<Name>). The MSI installer
seeds those under "NetBird"; with the previous "netbird-ui" Name the app
would have written under a different identity and the toast activator
CLSID the installer pre-registers would have been orphaned.
