feat(egress): memorable-recall row in gstack-egress grants

`gstack-egress grants` promises every standing consent in force with the
command that revokes it. The Memorable bridge's memorable_recall key is
one, so it gets a row: off by default, granted only when
`gstack-memorable enable` set it, revoked by `gstack-memorable disable`.
