fix(route-builder): use Swisstopo elevations for snapped routes

routeWaypoints passed BRouter's coarse, SRTM-based inline elevations
straight through, and the client only queried Swisstopo when a point
lacked an altitude — so snapped routes never hit the Swiss terrain model
and shipped a jagged profile that disagreed with the densified off-trail
path. Overwrite every routed point with enrichElevations (geo.admin.ch),
keeping the router's value only as a fallback where Swisstopo returns null
(hikes abroad). Disk-cached by coordinate list, so repeat snaps stay free.
