Deep-copies omitted field values with deepCopyObjectSimple so nested JSON arrays keep their shape and protected nested fields retain their stored values. Adds integration coverage for partial updates and draft saves.

Fixes #13853
Fixes #18415

Supersedes: closes #17713, closes #18203, closes #18426.

Related:

• fix: deep-copy omitted field values from the original document (3.x) #19424 backports this to 3.x and supersedes fix: preserve nested arrays in cloneDataFromOriginalDoc #17492.
• fix(drizzle): use structuredClone in cloneDataFromOriginalDoc to preserve nested arrays #17888's cloning fix is covered here, but it also contains unrelated changes.

Preserve nested JSON arrays

I chose bulk Publish because it sends only { _status: 'published' }, leaving the JSON field out of the request. That triggers the faulty fallback copy and clearly demonstrates that an unrelated update corrupts untouched data.
