Overhaul of the frontend on waiters, orders, and payment events

Manager Dashboard: product reorder/bulk actions, preference sub-choices
UI, expanded reports with DateInput component, waiter management updates,
order detail improvements, Docker config and backend dockerignore added.

Backend: table groups, auto-numbering, has_active_order flag, expanded
reporting endpoints, waiter zone management, user schema updates, system
router additions, table router fixes.

Waiter PWA: TableDetailPage order/payment event improvements.
