feat(nav/map): frame the trail, clamp distant waypoints to the edge

Browse Source 
While a trail exists the map now fits the recorded route (plus the live
position) and no longer folds waypoints into the bounding box, so a far-off
waypoint can't zoom the view out and squash the trail. Waypoints that
project outside the framed area are clamped to the nearest edge (marker +
label) instead of being lost off-screen. With no trail, the view still
auto-fits to the waypoints as before.

**Dropping a waypoint** — **Hold Enter → Mark here**. This captures the current GPS fix and opens the on-screen keyboard for a short label (up to 11 characters — e.g. `CAR`, `CAMP`, `H2O`). Leaving it blank auto-names it `WP1`, `WP2`, … Marking works whether or not the trail is being recorded; it needs a GPS fix (otherwise it reports *No GPS fix*).
**On the map** — saved waypoints show on the Trail Map view as a hollow diamond with the label's first two characters beside it (enough to tell nearby waypoints apart). The map's bounding box always includes them, so off-track waypoints stay in frame. Waypoints and your current GPS position are drawn continuously — even with no trail recording in progress — so the Map view doubles as a live "you + your marks" view, not just a recorded-track plot.

**Navigating** — **Hold Enter → Waypoints** opens the list (each row shows the label and live distance). The list always begins with a synthetic **Trail start** row whenever a trail exists, so you can backtrack to where you began without having marked it.
