Rewrite the Settings screen in short British English and remove the
duplicated paragraphs, keeping every control, binding and preference key as
it was.
- Fuel Savings: one-line descriptions for Best Value, average fuel economy,
fill-up amount (worded for the unit in use) and minimum saving; one concise
general explanation replaces the long footer; the orange "New comparison
basis" notice is removed.
- Units: "Station sign" becomes "Pence per litre"; the combined paragraph
becomes two contextual descriptions.
- Distances: "Accurate distances" becomes "Driving distances" with a short
description; the route-request and search-radii paragraph is removed.
- Tap action: "Open map"/"More info" become "Directions"/"Station details"
with a short description.
- Data checking: Standard and Smart summaries cut to one line each, one shared
background-update note, duplicated footer removed.
- Replay onboarding: shorter description. Support FuelBoard untouched.
Copy and layout only: no calculations, ranking, refresh schedules, stored
values or persistence changed. New and reworded literals live in
FuelBoard/en.lproj/Localizable.strings.
