Station detail: one verdict capsule, the chosen price style, and the working explained

The Best Value card states its verdict once. The badge is now the large capsule form the sheet used to repeat on its own line, so the same headline no longer appears twice, and the comparison caption ("vs closest station" / "your baseline") sits under the capsule — on the card and on the listing rows alike. The row's size-class split, which put the caption beside the capsule at regular width, is gone, so the pair reads the same on every device.

The facts row's price now follows Settings -> Units -> Price display. It called FuelStore.priceText(price, style: .stationSign) with the style hardcoded, so a Pounds & pence user still saw the bare forecourt figure under the map. It now uses priceTextAttributed with the style passed down from the list that opened the sheet (ContentView, StationsView, FavouritesView) — the same call the listing row makes, at the same @ScaledMetric(relativeTo: .title2) 22pt so it still scales with Dynamic Type.

"How Best Value works" gains a step-by-step section in plain English: the baseline and why it is the closest station by journey, the return trip and why the extra return travel can read larger than the one-way distance, the extra driving cost, the fuel-price saving, the total and its inversion when the drive costs more than the price saves, and where the minimum saving is set. Every statement matches the arithmetic in FuelSavingsCalculator. The sheet opens at 72% instead of 42% to give it room.

No calculation, ranking, wording or data source changed: comparisonLabel, priceTextAttributed and the shared FuelSavingsResult are the same calls they were.
