Rama main · réplica de lectura del repositorio original.

- **The native Word and Sheet editor no longer turns read-only on its own after a brief browser stall (#4801).** When the cached lease expiry lapsed before the editor read the server's renewals, it stopped writing although the server still confirmed the holder. A lapsed expiry now asks the server once. Writing continues only on a fresh confirmation; loss, an invalid reply or a failed check still stops writing and keeps the draft.
