Use document views in file processing and history

Replace broad entry inputs with the information used by file processing,
history, and JSON comparison. Separate customisation content and save-base
results from database-document models, and keep content fields out of
logical-deletion Metadata while preserving the parent revision.

Record the accepted design, compatibility boundaries, and verification.
Requires Commonlib commit 751b29a74340da57122b8ab11b80d00c40272120.
The registry dependency remains at 0.2.3 pending publication and adoption.
