fix(ansible): harden AUR install task and rename ansible_user to local_user

- AUR task: replace loop with single paru call, use changed_when: false
  (stdout-only match never fired under non-TTY runs) and failed_when: false
  so transient AUR failures don't abort the play
- Rename ansible_user -> local_user to avoid shadowing the connection
  magic var; update the two references in roles/common/tasks/main.yml
