Lightning.Projects.Events.ProjectDeletionScheduled (Lightning v2.19.0-pre)

The project was scheduled for deletion, so nobody may work in it any more.

Project-wide rather than user-scoped, like SupportAccessUpdated: scheduling removes no membership row and revokes no token, so that refusal is the whole of the offboarding gate during the purge window and it applies to every actor in the project at once. Nothing a later change can do makes a wound-down project writable again, so sessions holding it end rather than being re-permissioned.

The counterpart restore (cancel_scheduled_deletion) needs no event: sessions were ended, not degraded, and a rejoin resolves permissions fresh.
