feat(pricing): the server prices app orders with legacy's making-charge formula (MON-08)

Legacy: final % = variant % + customer % − the largest active promotion on the product, its category or its brand; rial charge 0. The apps sent the variant's own % only, so the new app undercharged by the customer's percent (usually 3) and ignored promotions, and the server trusted whatever the app sent. - pricing/wage-formula.ts: one formula, legacy by default, with coefficients, promotion pick, constant, floor/cap and rounding so the admin screen can change it; validated - an app order is priced by it; the app's wage, discount and rial charge are ignored; an operator's manual numbers are kept - POST customer/me/wage-quote; both apps show that figure - admin/pricing/wage-formula (config.wage): read, preview, approve with the sample it was checked on, last 20 versions kept; the setting is kept off the generic const routes Owner approval: 2026-10-08.
