/**
 * PR10 - audit log search.
 *
 * Validates:
 *  1. Tsvector full-text search via the GENERATED `search_text` column
 *  2. All filters compose: entityType, action, userId, entityId, date range
 *  3. Cursor pagination on (createdAt, id) yields stable, complete pages
 *     and never duplicates rows across page boundaries
 *  4. Per-port scoping isolates results
