Add-on rows already carried quantity, unit and extended price; only the name
was exposed. The attribute now renders the full line and a new monetary
sensor reports the add-ons subtotal separately from the box.
The fixture totals were copied from a seven-add-on cart while the fixture
itself had one, so they are now self-consistent and a test asserts that
add-ons plus box price equals the portal's subtotal.
Reads delivery day, next arrival date, both upcoming carts, box contents,
add-ons and order totals from a single /p/dashboard/details fetch. Adds five
sensors and parser tests over a synthetic fixture mirroring the live markup.
Records two portal quirks: every /p/ path returns 200 so signed-in state is
detected by a Sign Out control, and cart-contents-skipped marks the locked
cart rather than a skipped order.
