fix(layers): report Directions errors as English data

The Directions row errors (pointer blocked, no route, routing timed out,
no response from the routing service) and the route request failures
("Routing failed: {error}", "{error} — try again in a moment",
"Routing unavailable (HTTP {status})", the rate-limit and fallback
texts) were translated inside getStats(), so the layer snapshot that
voice tools and the analyst read carried Spanish or Russian text.

Fixed texts are marked with msg() and the interpolated ones are built
in English. The Layers panel translates them where it shows them,
through a ROUTING_ERROR_PATTERNS block in statusText.js that the
proxy's refusal texts move into. English reads as before. In other
locales two things differ slightly: a proxy text inside "Routing
failed: X" that is not one of the known refusals is now looked up in
the catalog instead of shown as given, and the "— try again in a
moment" shape is recognised on every layer's error, not only on
Directions.
