fix(ghostmaps): follow-up review fixes for the age switch

- Keep the open card across a widened reload only when its index still
  holds the same report; the server may answer a pinned version with newer
  bytes.
- Narrowing to a window the loaded data already covers clears a failed
  wider reload, so the row no longer stays in error.
- Label the every-age option "All" (contextual) so the six-option switch
  fits the row in every locale; tooltip and info line keep "All markers".
