Lists access review campaign executions bucketed by state. Completed and archived executions include the
file IDs of their auto-generated report ZIPs (per-app CSVs, and per-app PDFs), which can be downloaded via
the GET /files/{id}/download endpoint. A null file ID on a completed execution means the report
is still being generated — retry shortly. Archived executions hold partial reports for campaigns that were
cancelled or archived before completion. completedExecutions includes runs concluded early by an admin.

Ordering: every bucket is newest-first. Each bucket returns at most limit executions
(default 100, max 1000) — a bucket holding exactly limit items may have older ones beyond it;
raise limit to fetch deeper history. Use completedAfter to poll for newly completed
executions — it returns only executions whose completionTime is strictly after the given timestamp.
