refactor(ui): extract shared helpers, dedup screens, GPS shutdown via provider

Pull repeated UI idioms into DisplayDriver and remove duplicated logic:

- DisplayDriver: add drawScrollArrows() and drawInvertedHeader(); replaces 11
  copy-pasted scroll-arrow blocks across 5 screens and 3 inverted title-bar
  blocks (NearbyScreen x2, NavView). Standardises the detail-view separator.
- useImperial(): single source on UITask; NearbyScreen/TrailScreen delegate
  instead of each re-reading NodePrefs.units_imperial.
- NearbyScreen: extract saveSelectedWaypoint() (two identical blocks -> one);
  drop the redundant local label buffer (WaypointStore truncates).
- UITask::shutdown(): power GPS off through LocationProvider::stop() instead of
  poking PIN_GPS_EN directly — centralises enable/reset-pin + active-level logic.

Net -58 lines. Verified: GAT562 (SSD1306) and WioTrackerL1Eink (GxEPD) solo
builds compile clean.
