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.
