The configuration docs claimed it is not possible to add someone to a
team without them accepting an invitation email, but the backend
auto-adds existing profiles to the team when the email verification
is disabled (create-invitation in app.rpc.commands.teams-invitations).
Replace the incorrect sentence with an accurate exception note, add
the missing disable-email-verification entry to the "Other flags"
reference, document the CLI-created profile auto-add behavior in the
docker getting-started guide, and describe the shortcut in the
developer authentication docs.
