ansible: scaffold dangerousthings.authforge role skeleton

Adds meta/main.yml (Galaxy metadata for Ubuntu 22.04/24.04 under the
Apache-2.0 license), defaults/main.yml covering the policy/storage/
firstrun/pending knobs the tasks layer will consume, and a single
restart-daemon handler. Tasks and template land in the next commit.
