[LiveComponent] Invalid CSRF token exceptions are not correctly managed

[kbond]

Ok, so it's not the form's csrf that's causing the problem but the live component's csrf...

I agree we should provide a better method to handle this but not quite sure how yet. I think, currently, you can handle with a component js hook but it would be complex. Feels like we could use something similar to loading states but for errors.

@kbond thanks for the idea. Possible workaround here : symfony/symfony#51724

Not sure it would be a solution viable for the entire "symfony stack", but in UX packages, i think a lazy load of the CSRF would not be too hard ... and (yeah i'm a broken record) this would help performance / sobriety. (the CSRF token on public page restrict the caching strategies)
