Content drawn under the title separator touched the line on every standard
screen, because listStart() == headerH() (the row right after the separator).
Graphical screens worked around it with a hand-rolled hdr+2.
Bake a 2px breathing gap into listStart() so every list gains it at once, and
switch the screens that hand-rolled the offset (Compass, Nav, Nearby detail) to
listStart() so the content top is computed the same way everywhere.

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.

Add a single "Units" choice (Settings › System: Metric / Imperial) that
governs every distance and speed shown in Tools — Nearby Nodes, the Trail
views, and the navigate-to-point screen.
- NodePrefs: units_imperial (global) + trail_show_pace (Trail readout mode),
schema bumped 0xC0DE0005 → 0006. The old combined trail_units_idx is kept
for file-layout stability but no longer drives anything; upgraders default
to metric + speed.
- geo::fmtDist gains an imperial mode (ft below ~1000 ft, then miles).
- NavView / Nearby / Trail (waypoint list, Summary distance, List deltas,
map scale-bar label) all format through the global preference.
- Trail's action-menu "Units" row becomes a Speed/Pace readout toggle; the
km-vs-mi unit now follows the global setting instead of being one of four
combined options.

Phase 4. Header-only navview::draw() takes a target (lat, lon, label) plus
the caller's own fix and course-over-ground, and renders distance + two
absolute bearings (To / Hdg). Source-agnostic so Waypoints, Backtrack and
Nearby node nav all reuse it. Not wired in yet (phases 5-6).
