feat(groups): editable description, and one source of operator authority
A description could only be set the moment a group was created, so every group made before anyone thought of one stayed blank for good. The owner can now edit it from the group's page, and PATCH /v1/groups/{id} takes it. That endpoint takes the description and nothing else, deliberately. The name, the visibility and the join policy are the terms members joined on; a private group that can quietly become public is not the group they agreed to be in. Changing those needs a decision about who gets told, not a field on a form — there is a test saying so. Separately, the legacy operator key is gone. `admin_pk_ed25519` in node.toml named the operator before the roster existed and was kept so that an existing deployment would keep working; nothing uses it, and a second source of node authority is not something to carry around out of politeness. Authority is the roster, read fresh on every check. It is removed rather than ignored: a config that still names the key gets a warning at startup pointing at the file. Dropping it in silence would refuse invites and file deletion with a signature error that looks like a bug somewhere else — which is exactly how finding M3 presented. Two tests were verifying admin operations by naming a key in the context, which was the legacy path. They now pair an operator into a roster, the way an operator does. The authority test anchored on the deleted function and passed vacuously once it disappeared; it states the invariant against the verifier and the daemon instead. Also defined .btn-secondary, used in four places and styled in none. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
