polish(nav): tidy parseLatLon precision + ping-menu edge cases

Browse Source 
- geo::parseLatLon now rounds lat/lon in double (matching the Add-by-coords
  form) instead of through a float cast that lost ~1 m near 1e8.
- NearbyScreen: preserve the ping menu's selected row across a rebuild
  instead of snapping back to "Send" when a result line arrives.
- NearbyScreen: guard the ping-menu input path so a vanished contact
  (selectedStoredPubKey == false) closes the popup rather than acting on an
  uninitialised pub-key buffer.
