P1: Favourites Trends graph — FuelHistoryStore + TrendsView (Swift Charts)

Browse Source 
- Shared/FuelHistory.swift: GitHub mirror read path (latest.json pointer +
  history/YYYY-MM-DD.json day files); day math (UTC noon keys), slim day decode
  with the shared price band, series + deltaSeries (vs-cheapest rebase),
  favourites-only app-group cache (90-day prune), parallel per-day fetches,
  404/network = graph gap never error.
- FuelPriceProvider: shared priceBand + mapGrades (single source for live +
  history decoding).
- FuelBoard/TrendsView.swift: line chart in the Favourites tab via toolbar
  button + sheet; fuel capsule (fuels with favourites only), 7/30/90 range,
  Price/vs-cheapest toggle, per-station legend, price-display style on y-axis,
  empty/loading/retry states with honest copy; no widget in v1.
- Localizable.strings: Trends keys.
- 83 tests (13 history + URL regression): day math, band guard, series gaps,
  delta rebasing, prune, and the appendingPathComponent regression (relative
  URL resolution dropped /main — all fetches 404'd).
- Sim-verified: favourites rows + TOP/deltas; sheet controls + building-up
  state with live first-snapshot date (archive has 1 day; lines render once
  >=2 snapshots).
- Backlog: P1 Trends DONE (unmerged); P0 REMAINING = live provider chain +
  telemetry beacon.
