migrate: replace Supabase REST with Drizzle/pg in 28 more files (wave 5 final)

- admin components: TaxDashboard, OrderTableBody, TaxQuarterlySummary, StopProductAssignment, StopTableClient, ProductAssignmentForm, StopMessagingForm
- api routes: wholesale/checkout, wholesale/price-sheet, api/supabase (DELETED), api/reports/export, route-trace/* (stubbed - feature retired)
- lib: src/lib/supabase.ts (mock-only shim, no @supabase imports), src/lib/supabase/server.ts (DELETED)
- actions: wholesale-auth (stubbed - awaiting Auth.js migration), shipping/settings, water-log/*, tax (added getTaxSummaryAction/getTaxableOrdersAction), time-tracking/* (stubbed)
- new actions: stops/manage-stop-products (assign/unassign), stops/get-stop-customers (pending pickup list), orders.toggleOrderPickupComplete (legacy column)

All Supabase REST calls replaced with Drizzle ORM, raw pg.Pool queries, or
existing server actions. Typecheck: clean. Tests: 22/22 pass. Build: OK.
