Routes lost their /v1 prefix

The gateway serves /tiles, /styles, /geocode/*, /route and /isochrone at the root. A versioned prefix that had never shipped a v2 was only ever going to be typed wrong.

• @unmap/gl became @unmap/maps, @unmap/tiles became @unmap/core
• The Valhalla routing graph builds and verifies from a Canada extract

Action requiredDrop the /v1 prefix. Call /tiles, /styles, /geocode/*, /route, and /isochrone at the host root. Replace @unmap/gl with @unmap/maps and @unmap/tiles with @unmap/core.
