feat(nav): add a waypoint by typing coordinates

Browse Source 
New Trail action "Add by coords" creates a waypoint without a GPS fix: the
keyboard takes a "lat,lon" string (decimal degrees), parsed by the shared
geo::parseLatLon; on success it falls through to the normal label keyboard
(blank → auto WP<n>). Useful for a meeting point or a spot read off a map.
Invalid input reports "Bad coordinates".

**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*).
**Adding by coordinates** — **Hold Enter → Add by coords** lets you create a waypoint without being there: type `lat,lon` in decimal degrees (e.g. `37.42123,-122.08456`), then a label. No GPS fix is required — handy for entering a meeting point or a spot read off a map. Invalid input reports *Bad coordinates*.
**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). 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. With **no trail**, the view auto-fits to your waypoints and position. **While a trail exists**, the view frames the recorded route instead, and any waypoint that falls outside it is clamped to the nearest map edge — a distant mark can't blow up the scale and squash the trail.
**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. Select a row and press **Enter** to open the navigation view:
