cli, organization: org config and org instances commands, old business spelling kept (rename r2 stage B2)

mosaic org config validate|resolve runs runConfigCommand
(packages/organization/src/config-command.mjs), the callable service the
old mosaic business validate|resolve executable now calls too. The service
returns the exit code, never exits the process and does nothing on import.
The spelling sets only the stderr prefix and the usage text; status and
stdout are byte-identical, and the v1 output keeps the business key.

mosaic org instances|instance|veto takes the same arguments as
mosaic business instances|instance|veto and runs the same proof-bearing
instances command. It is dispatched before orgCommand, so it never builds
the dev-local-owner context. mosaic org validate FILE is unchanged.

Help, the UI labels for agent actions and instance reasons, and the
current docs now use the org spelling and the packages/organization paths.
Two webui test regexes follow the label text. packages/cli/tests/
rename-b-commands.test.mjs compares the two spellings golden for golden
on status, stdout, stderr and authorization outcomes, and covers a draft
file named like an installed ID.
