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.

- brouter-mock.ts: Canned route responses for 2 and 3 waypoint sessions,
plus latLngToPixel helper for pixel-precise map interactions
- planner.test.ts: Route split, map zoom, and overnight tests now use
mockBRouter() for instant deterministic responses instead of real
BRouter — fixes all 3 flaky tests
- Used .first() for sidebar km locator to avoid strict mode violations
when both header summary and stats footer match
All 38 E2E tests pass in 9.7s (was 34s+ with real BRouter).
