feat(puth/laravel): extended Browser functions

[SEUH]

• functions for livewire components (selectLivewire, typeLivewire) because livewire syncs after input event, sometimes you need to wait for sync to finish
• assertSeen: waits until a selector is visible, then waits until selector is hidden. useful because puth is sometimes too fast, e.g. after clicking a button, if you expect a loading spinner and only wait until that spinner is hidden, it can happen that the frontend didn't render the spinner yet, therefore waitUntilMissing will be true immediately
