DocumentViewSet.get_queryset() always attached a correlated subquery
resolving each document's latest version content, even though it's only
needed for the deprecated search/title_content/content__* filter params.
Evaluated for every candidate row before pagination's LIMIT, this is
pathological on MariaDB: its default cardinality estimate for the mostly-
NULL root_document_id self-join drives it to a near-full-table scan per
row instead of using the FK index, turning a normal filtered list request
into a multi-second query (root cause of paperless-ngx#13778's report).
Only attach the annotation when a request actually filters on it. The
common case now relies on Document.get_effective_content()'s existing
prefetch-based fallback instead (extended the "versions" prefetch to
include content), which DocumentSerializer.to_representation() now calls
directly instead of checking for the annotation via hasattr().
