Refactor Ansible tasks to use fully qualified module names and improve code consistency

- Updated all tasks to use fully qualified module names (e.g., ansible.builtin.shell, ansible.builtin.copy) for clarity and to avoid ambiguity.
- Replaced deprecated 'yum' module with 'dnf' for package management on RedHat-based systems.
- Improved formatting and consistency in task definitions, including the use of double quotes for strings and consistent indentation.
- Removed unnecessary comments and whitespace to enhance readability.
- Ensured that conditions and loops are consistently formatted across all tasks.
