Once SERVER-128507 , SERVER-128508, and SERVER-128509 are complete, we should add tests that combine all three operation types (insert, update, delete) within a single transaction and a single batched write.

Currently, tests for featureFlagContinuousInternodeValidationPerDocument cover inserts, updates, and deletes in transactions and batched writes separately. However, a real workload may interleave all three operation types within the same applyOps. This ticket covers writing tests that:

• Perform a mix of inserts, updates, and deletes within a single multi-document transaction and verify that doc hashes are present on entries with a replicatedRecordId and absent on entries without one.
• Perform the same mix within a batched write (WriteUnitOfWork::kGroupForTransaction) and verify the same invariants across all inner applyOps entries.
