Click any vehicle on the map to open a 360px slide-in panel showing:
- reporting time (first ACC_ON of the day)
- day totals: trip count, distance, drive/idle/stop minutes
- per-trip rows with start/end/duration/distance/idling, click to
select; selected trip renders its polyline + animates a marker
along it over 10 seconds
- end-reason badge per trip (work stop, reporting silence, long gap,
day end) with colour-coded accent
- date picker (defaults to today EAT)
- CSV download button → /trips.csv?date=...
Map clicks query rendered features across circle/arrow/label layers and
take the topmost — single click handler, no per-layer duplicates. The
existing hover popup remains untouched.
Wraps #map in #map-container so the panel can absolute-position over
the right side without disturbing the existing left-aside grid layout.
authClient gets a getToken() helper so the CSV download path can attach
the Authorization header for a plain fetch (apiFetch returns JSON only).
