getAccessValues() static cache ignores translation language, causing wrong domain grants for multilingual node

Problem/Motivation

The method DomainAccessManager::getAccessValues() uses a static cache keyed only by entity type ID, entity ID, and field name. It does not take the entity's language into account.

When called on translated nodes, the first translation cached is reused for all subsequent translations. This results in incorrect domain values being returned for translations. As a result, hook_node_access_records() writes incorrect entries into the node_access table, which leads to access being denied for otherwise published and properly domain-assigned translations.

Steps to reproduce

1. Enable Domain and Domain Access submodule.
2. Create a node in language A, assign it to Domain X.
3. Add a translation in language B, assign it to Domain Y.
4. Inspect the node_access table or attempt to view the translation as an anonymous user.
5. The translation is either inaccessible (403) or the node_access rows show the wrong domain assignment (Domain X instead of Domain Y).

Proposed resolution

• Extend the static cache key in getAccessValues() to include the entity language code.
• Example change:
  

      $langcode = $entity->language()->getId();
      if (isset(self::$staticCache[$entity->getEntityTypeId()][$entity->id()][$field_name][$langcode])) {
        return self::$staticCache[$entity->getEntityTypeId()][$entity->id()][$field_name][$langcode];
      }
      ...
      self::$staticCache[$entity->getEntityTypeId()][$entity->id()][$field_name][$langcode] = $list;
      

• This ensures each translation stores and returns its own domain access values correctly.

Remaining tasks

• Provide patch and rerun test suite.
• Add test coverage for multilingual nodes with different domain assignments per translation.

API changes

DomainAccessManager::getAccessValues() static cache structure changes (adds a langcode key). Existing callers are unaffected.

Data model changes

None.

Release notes snippet

Fixed a bug where multilingual nodes could receive incorrect domain access grants because getAccessValues() ignored translation language when caching. Sites using multilingual content should run node_access_rebuild() after updating.
