Categorise OSM passes by highway and colour them on the ride detail map

Passes are extracted from OSM PBF nodes (mountain_pass=yes) and linked to
containing ways; highway road values map to road, track to track,
path/footway to path, plus hiking for rock/climbing. All passes are kept,
coloured distinctly (road/track/path/hiking/unknown) for road-bike validation
on ride 397. Single squashed migration adds category column, cheap to re-extract.
