fix(release): 0.2.8 harden admin proxy, cart stock caps, selfpay and refund timeline

- admin proxy: 25s timeout, body guards, structured failure logs
- cart: addItem enforces stock cap (409 INSUFFICIENT_STOCK), UI clamps qty
- tpv selfpay: hide sidebar/discounts/save-pending, rename button, receipt-settings 400 fix
- pos admin: quick products slot count aligned to 8
- returns: human-readable history message + metadata jsonb (migrations 064-065) + admin fallback formatter
- storefront: product card white background
- product page: remove duplicate stock label under add-to-cart button
