feat(route-builder): clearer map cursors, route click tolerance, swisstopo credit

- Pointing-hand cursor over the map (click adds a waypoint); grab/grabbing
  only on the draggable waypoint pins. Fixes the cursor living on the
  Leaflet container element itself (the `.edit-map` div), not a descendant.
- Route polylines render on a canvas renderer with a hit `tolerance`, so a
  click near the line inserts a waypoint without a pixel-perfect hit.
- Hide the on-map attribution control and show the required "Kartendaten ©
  swisstopo" credit in the page footer, matching /hikes.
