* fix: dispatch toast action and reply events from WinRT activation path

ToastEventHandler::Invoke previously returned S_OK without dispatching
whenever the activation arguments looked structured (type=action,
type=reply, or contained &tag=), on the assumption that the COM
INotificationActivationCallback::Activate path would deliver the event
instead. That assumption only holds when Windows actually invokes the
COM activator — which it does for MSIX-packaged apps launched cold, and
for unpackaged apps with a properly-registered CLSID when the app is
not already running. For non-MSIX apps with activationType="foreground"
while the app is running (the common case), Windows raises only the
in-process WinRT Activated event, so action and reply were silently
dropped.

Dispatch structured activations through the same HandleToastActivation
the COM path uses. User input (reply text, selection values) is pulled
from IToastActivatedEventArgs2::UserInput, which carries the data the
COM callback would otherwise have received via
NOTIFICATION_USER_INPUT_DATA.

Also drop the &tag= term from the structured-args check. Plain clicks
in Electron-generated XML don't carry tag=, and a custom toast_xml that
puts tag= on a click argument should now dispatch as a click rather
than being silently dropped.
