feat: Implement Debian VM template creation and cloning on Proxmox

- Added default configuration for VM creation in defaults/main.yml.
- Created tasks for configuring the VM with UEFI, TPM, disks, GPU, and Cloud-Init in tasks/configure-vm.yml.
- Implemented clone creation and configuration logic in tasks/create-clones.yml.
- Added template conversion functionality in tasks/create-template.yml.
- Developed base VM creation logic in tasks/create-vm.yml.
- Included image download and caching tasks in tasks/download-image.yml.
- Introduced utility tasks for common operations in tasks/helpers.yml.
- Organized main orchestration logic in tasks/main.yml, with clear stages for each operation.
- Added pre-flight checks to validate the environment before execution in tasks/preflight-checks.yml.
