Refactor: Migrate deprecated Ansible facts to ansible_facts[] syntax

Why:
- Ansible 2.20+ deprecates INJECT_FACTS_AS_VARS and direct usage of top-level ansible_* facts.
- This change updates all affected roles and vars files to the new supported syntax.
- Ensures compatibility with upcoming Ansible 2.24 removal of implicit fact injection.
