fix: workbook queries - dedup tokens, MapHandler-only doc count, inner join for file types

- Token Usage by Model: use max() dedup per process_id to handle duplicate events
- Overall Summary: count documents only from MapHandler process_ids
- Token Usage by File Type: use inner join to exclude process_ids without mime type
- Daily Processing Volume: count only MapHandler process_ids
- Fix queryType to 0 (Azure Monitor Logs) and add TimeRange parameter
