feat(admin): redesign order list and detail workspace

Replace the type/method tab rows with status views backed by one GROUP BY
count, move filters into a single toolbar card, show gateway names, keep
list context across detail and actions, and split the detail page into a
summary/timeline column and an actions/buyer/note sidebar. Confirmations
move to admin-orders.js; PayOrders splits into flat List/Detail traits.

Remove dead code: unused Order AJAX endpoints and init(), get_orders_count(),
shipping flash codes, and the legacy raw-note fallback.
