inbound-antispam-panel: the backup holds the lists; Inbound log accepted

Step 7/12 of docs/plans/inbound-antispam-panel.md. A full backup walks
all of /data, so data/antispam/ was in it from the day the directory
existed; TestCreateIncludesStateExcludesTransient now holds that. On
the first start after a restore the maps are written again from the
database (mailStack.Resync, already there). The guide says what is not
in a backup: the antispam/ directory with the compose fragment and the
rspamd configuration, which is installation and not state.

The plan records the owner's acceptance of Inbound > Log (2026-10-12,
"Этот экран утверждаем") and what he changed on the way to it.

go test ./internal/backup/ ok.

 does not read `/data` and performs no version check. Start one normally
