fix(router): handle errors from view transition updateCallbackDone promise

Firefox-specific workaround: Firefox 144+ creates the `updateCallbackDone` promise
internally during error handling (e.g., duplicate view-transition-name), even before
the property is accessed. This can cause unhandled promise rejections to appear in
error tracking tools like Rollbar/Sentry. We must attach catch handlers to all three
promises immediately to prevent these unhandled rejections.
