rename dmc12 inventory to cloudlorean and vault admin_password

- replace inventory/dmc12.yml with cloudlorean.yml (+ group_vars) and update
  all README/AGENTS call examples and the inventory table
- move admin_password hash into encrypted vault.yml; remove plaintext copies
  from roles/bootstrap/defaults and group_vars/external.yml
- bootstrap.yml loads vault.yml via vars_files (same pattern as monitoring)
- monitoring: PSK config/registration updates, docker role defaults,
  os-updates logging/reboot refinements, ansible.cfg/execute.sh tweaks
- add .project-wiki knowledge base and .github agent instructions
