Maurice 1b5317a817 Give GPX tracks their own colour (#776)
Imported tracks all render in the same blue: the GPX/KML importers never
assign a category, so category_color is null for every one of them and
several walks in the same area are impossible to tell apart.

Adds a nullable route_color on places, kept out of the COALESCE group in
updatePlace so an explicit null can reset a track back to inheriting its
category colour. The hex is validated in the Nest controller rather than
in the shared contract: the update body is an open record on purpose, and
tightening it would mean removing PlacesController.update from the
ratchet-only body-contract allow-list.

The importers now hand each new track a colour of its own, picked from
the palette entries the trip is not already using. That happens in the
Nest service over the injected DatabaseService — the colour assignment is
new logic, and new logic does not belong in the legacy place service (see
server/src/nest/README.md). The field itself is only threaded through the
existing update/create statements, which the proportionality rule covers.

Also fixes duplicateTrip, whose explicit column list has been silently
dropping route_geometry all along, so a duplicated trip lost its tracks.
