fix(hud): ask again in the new language after an in-place switch

- _relocalize() now drops the received reply and aborts one in flight, so
  the next tick asks in the new language instead of keeping old-language
  text under the new-language state tag.
- The English-echo check also allows state words inside a place label
  (Estación Loading Dock).
- Reword the non-English instruction so it reads for every language name.
- Add the two new test files to the format scope.
