Listing rows: verdict text hugs its icon, and the address stops repeating the name

Two things the listing row was saying twice, or too loosely.

- The verdict capsule used a Label, and a Label lays its icon and title out
  across the width it is given: in a listing row that left 22pt of empty space
  between the symbol and "Save £1.07 after travel". It is now an HStack with
  an explicit 3pt spacing (5pt in the detail sheet), so the text sits beside its
  icon and the capsule background hugs the pair. Measured on the same row: the
  capsule text moved x 412 -> 341 and the pill 270-831 -> 270-691.

- The address line printed the station name a second time. The official Fuel
  Finder address field usually opens with the station's own name ("CHIDSWELL
  SERVICE STATION, LEEDS ROAD, DEWSBURY, WF12 7QW" for "Jet Chidswell"): 14% of
  the dump's addresses start with the exact name, and 13% also end with the
  postcode the row appended again. StationAddressLine (new, in Shared/, so the
  row and the detail sheet share one rule) drops a leading repeat of the name
  and writes the postcode exactly once.

The rules are deliberately conservative: a leading segment carrying a house
number is a real street address and is left alone ("41 ANNACLOY RD ANNACLOY"),
and a partial-word match ("Jet" against "JETSON FILLING STATION") never cuts
into a word. 14 new tests (169 total, 0 failures) pin the shapes found in the
real dump as well as the examples above.

Verified on the simulator: the first listing row's second line went from
"CHIDSWELL SERVICE STA..." to "LEEDS ROAD, DEWSBURY...", and the detail sheet
reads "Sainsbury's Halifax / WADE STREET, HX1 1SB".
