Upstream's hosted service is gone, so the "Vibe Kanban Cloud is shutting
down. Export your data within 30 days." bar is dead UI on a self-hosted
instance — it points at vibekanban.com/shutdown and there is nothing
behind it.
The banner arrived with the export feature (3733865, #3344) rather than
with the sunset commits, so it cannot be reverted wholesale without also
losing export. Both shells already gate it behind showCloudShutdownBanner,
so pin that to false and keep the export routes and handlers intact.
isExportRoute in RemoteAppShell existed only to feed that expression and
is dropped with it; the packages set noUnusedLocals, so leaving it would
fail the build. isProjectRoute, isExportActive and isSignedIn are all used
elsewhere and are untouched.
