feat(cli): add deployment mode prompts, auth bootstrap-ceo command, and doctor check

Extend server setup prompts with deployment mode (local_trusted vs
authenticated), exposure (private vs public), bind host, and auth config.
Add auth bootstrap-ceo command that creates a one-time invite URL for the
initial instance admin. Add deployment-auth-check to doctor diagnostics.
Register the new command in the CLI entry point.
