fix(accounting): gap detail queries referenced columns that do not exist

The drill-down queries were written against assumed column names and
every one of them failed, so "عرض التفاصيل" always answered "لا توجد
تفاصيل متاحة". Corrected against the real schema: pool zone bookings
have label/zone_row/zone_col and no zone table, player cards use
valid_from/issued_at and card_number, pool bookings carry booker_name
rather than a member join, and private match bookings store total_cost
rather than total_amount.
