Following the sort-segment rename, the rest of the user-facing "Worth the Drive"
copy moves to "Best Value".
- Settings: the toggle is now just "Best Value" (was "Enable Worth the Drive"),
and the narrative footer opens "Best Value estimates fuel cost only, …".
- More info sheet: the section header is "Best Value" (was "Worth the drive?"),
and the section itself is now conditional. `fuelSavings` is nil whenever the
feature is off — `savingsLookup` returns nil when it is not configured — so
the heading is never left dangling over an empty section while the feature is
disabled.
- The unavailable text reads "Best Value unavailable: …".
- Comments and doc comments that named the sort were updated so they match the
UI instead of contradicting it.
Deliberately unchanged: the enum's raw value stays `worthTheDrive`, so stored
sort preferences and widget configs keep decoding, and FuelSavingsStatus keeps
its verdict wording ("Worth the drive" / "Not worth the drive") — that describes
a station's verdict rather than the feature, and is not shown in the UI.
Verified on the simulator: with the feature OFF the more info sheet shows
Address / Distance / Directions and no heading at all; with it ON the sheet
shows the "Best Value" section; Settings reads "Fuel Savings" / "Best Value"
with no "Enable" anywhere. 172 tests, 0 failures.
