feat(ui): grouped thousands separators for price/amount inputs

Price fields showed raw digits (1490000) while typing — hard to read for
Toman amounts. New shared MoneyInput groups as you type (1,490,000),
accepts Persian/Arabic digits, and reports a raw digit string so callers
keep parsing unchanged. Applied to menu item price, branch price override,
expense amount, and payment-correction replacement amount. Displays already
group via formatCurrency (incl. the QR guest-menu preview).
