TagsField/CorrespondentField/DocumentTypeField/StoragePathField were
plain PrimaryKeyRelatedField subclasses with no batching. When used
with many=True (only tags today: DocumentSerializer.tags,
WorkflowActionSerializer.assign_tags), DRF's ManyRelatedField resolves
each submitted id with its own query, one query per tag on every
PATCH/PUT that sets tags.
Added BatchResolvingPrimaryKeyRelatedField as the shared base for all
four field classes and overrode many_init so the many=True form
(_BatchingManyRelatedField) resolves the whole id list with one
pk__in query, falling back to the child relation's normal per-item
validation for anything not found in that batch. Only TagsField uses
many=True today, but the fix isn't tag-specific -- if a future PR puts
many=True on one of the others, it inherits the same batching instead
of reintroducing this as a new bug.
