feat: start a project from another one's configuration

Creating a project can name one the creator owns or administers: its
statuses, transitions, types, areas, custom fields and automation rules
are copied once (paused rules stay paused; rules assigning to someone who
is not in the new project are left out). GraphQL templateProjectId, REST
template (id or key), MCP create_project template, and a select in the
web's new-project form.
