(ai_translate) One click translations for Layout builder

I have attempted to test this on a local install, and it looks to me like this doesn't work yet.
The problem I encounter is that only the title is translated, and nothing that was placed trough layout builder.

To me it seems like something that needs to be changed in the TextExtractor. Will investigate further.

If a field type is layout_section, the value always seems to be "Text" instead of the actual text I filled in in the layout builder content. That gets sent to the AI, but a new layout section does not get created either.

It seems like there are multiple things that can still be improved here.

array:1 [▼
  0 => array:5 [▼
    "delta" => "850c5e44-8e63-4435-a015-2556aa8c323d"
    "field_name" => "info"
    "field_type" => "string"
    "value" => "Text"
    "parents" => array:2 [▼
      0 => "info"
      1 => 0
    ]
  ]
]

I tested as well and it seem to work in the specific default case :
- The content type has a node "layout_builder__layout" wich is NOT TRANSLATABLE
- All the blocks used in Layout builder need to be translatable and have text fields translatable.

So in this configuration it will work as expected, it will just create a translation for the node, where the blocks ids are kept from the source language and translated.

It's the same idea as for the paragraph, this is a "symmetric" setup.

For my use case i would need to be able to have an "asymmetric" translation of the blocks for layout_builder (Dupplicate the block from source language, translate it and attach it to node translation).

I'll work on a module as i made for the asymmetric paragraphs : https://www.drupal.org/project/ai_translate_paragraph_asymetric

I made more intensive testing and the MR seems fine for me for a "classic" install as specified in my last comment.

For the layout builder configured to be asymmetric (with Layout Builder Asymmetric Translation), i created a contrib module to handle this case :
https://www.drupal.org/project/ai_translate_lb_asymmetric

With this module, you'll be able to translate you layout builder page with the following config:

- Translatable Fields: Ensure that the fields referencing blocks (layout) are configured to be translatable.
- Non-Translatable Block Fields: Make sure that the block fields themselves are not set to be translatable.

I fixed the phpcs et cspell issues.

Merged with latest dev to pass tests and then getting merged into dev. Thank you everyone.

This does not work for me.

Site default language: Dutch.
Additional languages: English and French.

Content type 'Page' has a layout_builder__layout field that is translatable.

I have sevaral block content types like hero, text, image etc. None of the block fields is translatable.
I'm using ai_translate_lb_asymmetric, layout_builder_at, ai, ai_translate
For AI model I'm using Claude Sonnet via ai_provider_anthropic

I create a page with sections, a hero block, some text blocks etc in Dutch (original language).
I click translate and translate the page to French via 'Translate using claude-3-sonnet-latest'.
It takes some time, but I successfully see a French page with all the same blocks as my original page and all texts translated (yeay!).
Now I switch back to my original page (Dutch) and I see that only my first (dutch) hero block is still working, all the rest of the blocks seem missing.

When I edit the layout, I don't see the missing blocks, but I see some sort of placeholder text where the blocks should be.
Edit: I created a separate issue for this: #3521109

@flyke Please open a new issue with your steps to reproduce your problems, thanks

We are doing some issue management housekeeping and adding/removing components.

We are removing the "Other Submodules" component and want people to categorize issues with the best module/submodule component.

Moving this issue to "AI Translate".
