Genesis Presets' para-id and the chain-extenstion para-id might diverge

Description of bug

In the genesis config presets we assume the established system chain para-id, as can be seen here. Yet, in the polkadot-parachain chain-spec, we also have to pass the para-id to the chain extensions, as can be seen here.

If one is not careful (as it happened to me 🙈 in https://github.com/paritytech/polkadot-sdk/pull/7476/files?notification_referrer_id=NT_kwDOAkHJB7QxNDYzNzE3OTM0MjozNzg2NTczNQ#discussion_r1959229620) it can be that a discrepancy is introduced.

It would be better if we allow passing the para-id into the genesis preset builder, so that we can cleanly propagate the para-id from the top to the very button.

I see you already found: #7384

So yeah, this issue is actually a duplicate.
