Add a new "Банкетное меню" catalog tab (category 6) alongside Боксы/
Премиум/Посуда for composing wedding/banquet/anniversary menus. Unlike
the other tabs, dishes here are priced and weighed per guest, grouped
by menu section (catalogSection), and clicking a checkbox doesn't add
to the order directly -- it toggles inclusion in a live summary panel
showing a running per-guest price table for the whole composed menu.
The item editor gets two new fields (menu section, weight per guest)
shown only for this category, reusing the existing generic item CRUD
(editBox/saveBox) rather than building a parallel admin UI.
Also re-bumped index.html's script cache-busting query string, which
the previous whitelist-fix commit changed the content of app-runtime.js
without updating -- the same stale-cache bug fixed earlier in the
session, now closed for directly-tagged scripts too.
