Honest pins and paths: geocode precision, type-gated paths, impossible-speed stops (#236)

Backend: _geocode_location now returns {lat, lng, location_type}, so the
precision rides onto the call doc and, unchanged via _resolve_location_pair,
onto the incident pin. Display-only: every correlator read indexes lat/lng.

Frontend: pins styled by precision (rooftop / interpolated ring /
GEOMETRIC_CENTER dashed uncertainty circle labelled with the spoken place /
unverified pre-#23 pins ghosted). liveWall.pathStops() is shared by the map
and the call spine: only police/accident incidents with a pursuit tag draw a
numbered path; others get unnumbered call dots. Segments over >10 min gaps or
talkgroup changes are dashed, stops implying >8 km/min are ghosted off the
path, paths >20 km get a "may be merged" badge. New optional MapView prop
pulseIncidentIds (wired by #238).
