Replace ProductAverageRevenueTable with TopProductsTable using direct transaction aggregation

[IanTheMitten]

Motivation

• Simplify the statistics view to aggregate metrics directly from sampled transactions and remove reliance on inventory-adjustment replay and product adjustments API calls.
• Surface actionable per-product metrics (rank, units, revenue, profit, margin) with a straightforward revenue-first ranking and optional secondary sorting.

Description

• Added src/components/statistic/TopProductsTable.tsx, which aggregates unitsSold, revenue, and profit from sampled transactions and computes margin as profit / revenue with a divide-by-zero guard.
• Default sorting is by revenue descending and the table includes optional secondary sort controls (metric + direction) for tie-breaking or alternate views.
• Removed src/components/statistic/ProductAverageRevenueTable.tsx and its inventory-adjustment replay and API dependency, and updated StatisticPage and App to use the new TopProductsTable signature.
• Rendered columns: Rank, Product, Units Sold, Revenue, Profit, Margin % and preserved sampled-day filtering via the existing sampling utilities.

Testing

• Ran npm run build and the production build completed successfully with no errors.
