The presenter detail page loads files with try_cache:false, which fetches
fresh data from the API but does NOT write it to Dexie (by design in the
SWR implementation). The file list's liveQuery then reads stale Dexie
records that lack event_session_type_code, causing the PDF→image convert
button condition to silently fail for presenter files in poster sessions.
Fix: trigger a try_cache:true background refresh on mount in the direct
wrapper so fresh API data (with event_session_type_code='poster') is
persisted to Dexie and the liveQuery re-renders with the correct field.
