Eligibility
This is a mechanical rename of the uid field to id across dashboard schemas and related code, with backward compatibility handling added. However, the author does not own any of the changed files, which are owned by multiple teams (@elastic/kibana-presentation, @elastic/appex-ai-infra, @elastic/actionable-obs-team), so designated code owners should verify the rename is implemented correctly.
