Allow limiting the amount of User data revealed to the client by Database Notifications

[iamjrock]

When using Database Notifications with websockets, by default all public properties of the User are exposed to the Client:

This can be resolved by adding Laravel's broadcastWith() method to the Filament\Notifications\Events\DatabaseNotificationsSent event as follows:

    /**
     * Get the data to broadcast.
     *
     * @return array<string, mixed>
     */
    public function broadcastWith(): array
    {
        return ['id' => $this->user->id];
    }

After doing this, we see the following in the client:

The suggestion is to introduce a way to use the broadcastWith() method when sending Database Notifications.

Maybe something like:

\Filament\Notifications\Notification::make()
    ->title('Punch it Mav!')
    ->sendToDatabase(
        users: auth()->user(),
        isEventDispatched: true,
        broadcastWith: [
            'id' => auth()->user()->id,
        ]
    );
