Remove pageSize cap from /find/aggHistory endpoint

Aligns with sibling /api/entitiesQuery/find, which serves entity pages
unbounded and is the endpoint paired with /aggHistory in the PE entity-
table export. Capping aggHistory at 100 while /find returns up to 1000
caused entity and aggregated-value lists to fall out of sync on export.
The expensive timeseries reads use tsService.findAllByQueries, the same
path as the WebSocket AggHistoryCmd, which has no such cap.
