No stock validation existed in the ordering flow, allowing customers
to order more items than available.
Cap quantity to ``stock_current`` in ``Baskets::getBasketData()`` when
adding to cart. Add ``min=1`` and ``max=stock`` attributes on the
basket quantity input, with JS clamping in the change handler.
Verify stock again in ``Shop\OrderController::store()`` before saving
the order as a race-condition safeguard.
Replaces the simple address radio list in the checkout page with the
richer ``Shop.Customers.partials.addresses`` partial already used on
the profile edit page. Customers can now choose among existing
addresses, add a new one on-the-fly, or delete an address directly
from the checkout flow.
Display a tailored confirmation message when the customer pays by
check or wire transfer, including a warning about the 30-day
cancellation policy. The payment type is passed as a query parameter
so the message survives page reloads.
- Add ``getOrderConfirmedByCheckContent()`` and
``getOrderConfirmedByWireContent()`` to ``Contents`` repository
- Flash ``payment_type`` through redirect query parameter
- Add migration inserting content rows (id 10, 11)
- Update confirmed view with green checkmark and warning icon
