Best Value: one price age instead of a source breakdown

Dated pricing had crowded More info and the station rows, and most of the
extra copy described a distinction the data cannot make: every station
carries a single station-wide timestamp, so "grade-specific vs
station-wide" never varied in practice.

- More info shows one row, "Price updated 28h ago" (or "Not provided"),
  replacing the separate station-report and fuel-update-time rows and the
  blanket "price freshness is not confirmed" label.
- Rows and the detail sheet stay quiet when a saving is shown; only an
  ineligible comparison explains itself. Provisional savings already read
  as estimates from the capsule, so the fuel-named warning lines are gone.
- Freshness/eligibility logic is unchanged: it still gates the baseline and
  still supports grade-specific timestamps for when the relay emits them.
- Tests updated; localisation keys for the removed copy dropped.
