Recursive dependent fields fix

[devnix]

This could probably fix #25

@ErwannDiagram, @toby-griffiths, I think this pull request would solve our problem. Could you provide feedback about it?

@alcohol, @aesislabs, would you like to check if it solves your case too?

TODO:

• Add e2e failing case for chained dependent fields
• Analyze and refactor src/DynamicFormBuilder.php diff since it was vibecoded

We've been successfully using this branch in production for a couple of weeks without problems. I've been trying to implement some e2e tests to replicate the issue with live components but I'm pretty lost about what would be the correct way to set it up.

If someone could help me to set up the environment, I would be more than happy to create the reproducer :)

@devnix I dont' know the exact steps to set up tests, but if you check out the API Platform skeleton this has e2e tests pre-configured, using playwrite… but now I thinkof it, you probably want PHP tests for this repo, right?

[devnix]

Probably yeah, I think I (we?) would prefer to use zenstruck/browser for that?
