feat: add per-trip use_gpx and autoconnect toggles

Adds two configurable toggles to the trip blueprint (Admin2 Trip tab):
- use_gpx: show/hide GPX tracks on all maps (default: enabled)
- autoconnect: draw connector lines between markers (default: enabled)

When use_gpx is off, GPX files are not fetched or rendered on any map
(home, map, trip, dailies). The stats panel in trip.html.twig still
reads GPX_URLS directly and is unaffected.

When autoconnect is off, buildJourneySegments suppresses all
auto-connectors; only entries with force_connect:true still draw a
line — making force_connect behaviour independent of both settings.

Also refactors the inline Promise.all in trip.html.twig to use the
shared renderGpxJourney utility (reducing duplication).
