BKP6: the put-off wait for a restore is a bound key of restic's state put-off; its expiry raises backup-waits and ends the wait

The record backed-up reads is the key `<module>.<item>` of the module's own state put-off (key-ttl), bounded by the setting
put-off-bound (minutes, default 60); the bus removing it is heard as the expiry, which writes the finding backup-waits through
the held writer over the module's findings and ends the wait, so the night never holds its lock without a bound. The file
put-off.json and its writes are gone. The manifest requires put-off, findings and finding-events and hears findings-asked.

Builds: design 47 G §561, §563, §557, §302, A-155, A-77
