Video Support

[JonPurvis]

Hey 👋

This PR lets you generate videos with the AI SDK, pretty much the same way it already works images. Here are some key points:

• Video::of() API, Same idea as images: describe the clip, tweak options, then generate() or queue().
• Queued generation with callbacks, queue() plus then / catch so long runs don’t block the request.
• Fakes for tests, Video::fake() and assertions in the same way as image fake can be used.
• Config hooks, Default video provider and an optional queue name; falls back to the normal default queue when one isn't set in the app.
• Gateway behind the provider, Video HTTP flow lives on the provider/gateway side which allows apps to keep using the Video entry point.

Code Example:

use Laravel\Ai\Video;

Video::of('A short clip of a city at night with neon lights')
    ->queue(provider: 'openai')
    ->onQueue('process-videos')
    ->then(fn ($response) => $response->storePublicly(path: 'videos', disk: 'public'))
    ->catch(fn (\Throwable $e) => report($e));

Demo:
(Note: The video is a bit jittery thanks to some crop tool I used, I also cut out all the waiting around, it's not actually this quick!)
