FileRepo.Update rewrites every editable column, so a PATCH that omitted a
field cleared it. Seed original_name and metadata — which have no always-
present input in the file editor — from the current file so a partial
update leaves them untouched instead of nulling them. The merge path builds
its own complete patch and calls the repo directly, so it is unaffected.
