fix(usage): fetch full trend/export series via page=-1

Trend charts and breakdown exports need the complete date series. The old
perPage=10000 workaround (and the missing page param on the token trend,
which fell back to perPage=20) dropped low-traffic — often most recent —
buckets, leaving gaps in the charts (#5690).

Send page=-1 (the backend's no-pagination sentinel) for the token trend,
the storage/instances trend charts and table exports, the resource export
dialog, and the summary-tab date trends.
