Widget: per-widget distance, sanitised names, £ prices

- New Distance picker in Edit Widget (5/10/15 miles), independent of the
  app's distance filter; used for both the relay fetch radius and the
  strict in-widget filter.
- Brand text is now title-cased via sanitizedStationTitle (relay sends
  all-caps brands like SHELL/TESCO/MORRISONS).
- Prices now show as £1.399 (monospaced) matching the app, instead of
  139.9p.
- Directions deep-link (mapsDirectionsURL) already per-row on medium and
  whole-widget on small; unchanged. 35 tests pass.
