selector: --org and --business in land-work

land-work takes --org as --business in one scope. A repeated, conflicting,
missing, empty or flag-shaped value exits 4 before the config is read. The
id keeps its old grammar (none): any other text names businesses/<ID>.json
and a missing file exits 3. A value of --subject or --attribution is never
read as a selector.
