Merchant daily performance summary drops transactions without a matching operator row #569

LoadMerchantDailyPerformanceGroups and LoadMerchantDailyPerformanceRecentSales now use an inner join on context.Operators.

Impact:

• Any transaction that does not have a matching operator row disappears from the summary
• Totals can undercount compared with the transaction data and the rest of the reporting code, which treats operator as optional in similar paths

Suggested fix:

• Use a left join / DefaultIfEmpty() if operator data is optional, and preserve the transaction in the result set.
