…ery (#8101) ## Rationale LabKey/internal-issues#1607 In the app React grid, we are sending two API requests: one for the page of data and a second for the total row count. Because the total row count API call sends maxRows: 1, we are getting an extra LIMIT 2 query on the server side prior to the COUNT(*) query. selectRows with maxRows=0 and an explicitly sent includeTotalCount=true now becomes a count-only request. The server runs only COUNT(*) (skipping the LIMIT 2 rows query) and returns rowCount, an empty rows list, and metadata only if asked for. loadTotalCount in withQueryModels now sends maxRows: 0 and includeMetadata: false. ## Related Pull Requests - #8101 - LabKey/labkey-ui-components#2081 - LabKey/limsModules#2501 - LabKey/testAutomation#3215 ## Changes - SelectRowsAction treats maxRows=0 with an explicit includeTotalCount=true as a count-only request - a new count-only path runs only the COUNT(*) and returns rowCount, metadata if requested - adds loadTotalRowsOnly(), which checks read permission and runs COUNT(*) without a rows query - getAggregates() no longer returns empty when no rows query has run
