fix: include ads-only ASINs in merge and use unfiltered rows for totals

1. Changed weekTotals to use 'rows' instead of 'filteredRows' so totals
   always show complete sums regardless of search/growth filters
2. Added second pass in mergeSalesAndAdsData to include ads records for
   ASINs that have ad spend but no corresponding sales data
