migrate: replace Supabase REST with Drizzle/pg in 11 more action files (wave 5 partial)

- analytics.ts: rewrite getReportsSummary, getRevenueChart, getSalesByProduct,
  getContactGrowth, getRecentOrders, getConversionFunnel against pool + new
  orders/customers schema. Drops retired columns (subtotal, pickup_complete)
  and re-implements the SQL by hand.
- import-orders.ts: bulk import via withTx using orders + orderItems + customers
  Drizzle tables, computes total_cents from current product prices.
- import-products.ts: rewrite to use withTenant(brandId) and Drizzle products
  table.
- products/create-product.ts, update-product.ts, upload-image.ts: switch to
  withTenant + Drizzle; image_url moves to product_images table.
- reports.ts: rewrite against pool + new orders schema.
- route-trace/lots.ts: stub functions (route-trace feature retired from SaaS
  rebuild — harvest_lots table not in db/schema). Uses discriminated union
  return types so consumer narrowing works in both branches.
- settings/features.ts: switch to withTenant + Drizzle brandSettings.
- shipping.ts: switch to pool + Drizzle orders/orderItems.
- api/v1/referrals/route.ts: fix typecheck (referred_user_id undefined → 'anonymous').

Typecheck: clean. Tests: 22/22 pass. Build: succeeds.
