Add road type color mode to route visualization

Browse source 
Extract highway=* tags from BRouter tiledesc messages alongside surface
data and add a new "Road Type" color mode that colors the route polyline
and elevation chart by OSM highway classification (cycleway, residential,
path, etc.). Includes color palette, legend, hover labels, i18n (EN+DE),
unit tests for tag extraction, and E2E tests.
