/**
 * Main entrypoint for restoring a document's field data from flattened form
 * back into the original nested structure.
 *
 * Always returns `{ data, warnings }`. Warnings carry per-row reasons (e.g.
 * "Invalid block index 'undefined'") that are typically the result of a
 * collection schema change leaving orphan rows behind. Callers decide what
 * to do with them — strict reads reject any non-empty `warnings`, lenient
 * reads (the admin edit path) surface them to the UI.
 *
 * @param fields - The field definitions for the collection.
 * @param flattenedData - The flattened field data to restore.
