Generate a multi-client usage report for [month/year]. Use the generate_sheet tool to create an XLSX workbook with:
- A "Summary" sheet with columns: Client, Plan, Credits Used, Credits Remaining, Requests, Amount Billed — one row per client
- One detail sheet per client with columns: Date, API, Requests, Credits, Status — showing weekly usage breakdowns
Include realistic data for [number of clients] clients with varied plan tiers.
