Refactor `InertiaResponse` to `Component`

[NeoIsRecursive]

I think this would be more aligned with tempest and would allow users to do either:

#[Get('/login')]
public function loginView(): Component {
   return inertia('auth/login');
}
// or
#[Get('/register')]
public function registerView(): Component {
    return new Component('auth/register', props: [...])
}

I'm not sure if this is possible yet, but I think it would make this more tempesty, (new Json(), new Forbidden() etc)
