Allow to translate entity reference fields that reference content

Problem/Motivation

Currently fields that entity reference gets added to the batch but doesn't get handled or translated. so this automatically translate referenced content entities (e.g., nodes) when translating a parent node.

Steps to reproduce

Proposed resolution

  1. Field Scanning:
    During the translation process, all fields of the node are scanned. If a field is of type entity_reference and targets the node entity type, it is marked for recursive translation processing.
  2. Referenced Node Loading:
    Each referenced node is loaded using its target_id. The system ensures the referenced node exists and is a valid content entity (i.e., an instance of NodeInterface).
  3. Translation Check:
    For every referenced node, the system checks if it already has a translation in the target language. If the translation exists, it skips further processing for that node. If not, it prepares to translate it.
  4. Cycle Detection:
    To avoid infinite loops caused by circular references (e.g., Node A → Node B → Node A), the system keeps a list of visited node IDs in the current translation chain. If a node is already in the visited_nodes array, it will be skipped to prevent recursion loops.
  5. Recursive Translation:
    If the node hasn't been translated and isn't in the visited list, its ID is added to visited_nodes, and the system recursively invokes the translation logic (e.g., via formTranslate()) to create its translation.
  6. Logging and Finalization:
    The system logs successful translations and skipped nodes (due to cycles or errors) for traceability. Once all referenced nodes are processed, the original node’s translation continues or finalizes.
