Paging used from/size, which OpenSearch hard-caps at index.max_result_window
(default 10000). Agents with more findings 400'd at from=10000, the whole agent
then read as '0 vulns' and its backfill was skipped — so hosts with 24k/27k
findings silently contributed nothing. Switch full syncs to the scroll API (no
window ceiling, no unique-sort requirement), with a fallback to windowed paging
if the indexer refuses scroll; explicit-offset callers keep from/size but stop
at the window instead of erroring.
Also hide the dashboard AI Audit controls + recommendations panel from
read-only users (the audit endpoint is editor-gated and threw 'Access denied').
