Restore an archived guardrail config

POST 
/v1/projects/:project_id/guardrails/:guardrail_id/versions/:version/restore

Writes an archived version's document back as the guardrail's live policy, which archives it again as a new version rather than rewinding the counter — so an approval item or exception citing any version in between still resolves.

The restore runs through the ordinary update path, so the archived document is re-validated; restoring the policy the guardrail already holds is a no-op and archives nothing.

The resource has moved past the version this write read (VERSION_CONFLICT): a stated expected_version or If-Match no longer matches, or a concurrent write took the version first. meta.current_version names the version in force. Nothing is written.
