[Fix] #0048244 UI/Prompt: async state roundtrips can break client JS (forms / scripts / close-redirect)

[fhelfer]

• Hardens Prompt JS for asynchronous state roundtrips (null-safe state sections, script replace marker, safer re-init / signal rebinding).
• Standalone bugfix; unrelated to confirmation / entity-input work.

Hi @fhelfer,

Thx a lot for the bugfix!

Please help me answer the following questions:

• Do I understand correctly that this addresses two separate issues? One being the availability of all sections which is not always the case, the other being the JS code that is provided async that is not always or ever considered?
• Could you look into whether we could replace the approach used inside the prompt JS using the DOMParser with the AsyncRenderer implementation of the UI framework? This should already take care of the scripts issue I think.

Thx for following up here.

Kind regards,
@thibsy (as UI coordinator)
