Livewire: Added ComponentNotFoundException to $dontReport

A bot was POSTing a crafted payload to that endpoint requesting the `filament.pages.dashboard` component - a known Filament probe - while posting to the . Livewire resolved the route, couldn't find that component class, and threw `ComponentNotFoundException` uncaught, resulting in a 500.

`ComponentNotFoundException` is now in `$dontReport` (so it won't flood our error tracker) and returns a 404 JSON response, the same pattern already used for `PublicPropertyNotFoundException`. The bot gets a 404 and moves on, no more 500s.
