Replace Molecule Proxmox component placeholder assertions with real tests

User Story:

As a developer, I want real test assertions for Proxmox component so that Proxmox operator functionality is validated

Problem Statement:

Proxmox component Molecule tests have placeholder assertions that don't validate VM operations, network configuration, or Ceph storage integration.

Acceptance Criteria:

• Proxmox CRD creation validated with correct spec
• VM creation and deletion operations verified
• Network bridge configuration tested (vmbr0, vmbr1)
• Ceph storage pool integration validated
• Resource allocation limits enforced.
• Template cloning operations verified
• Idempotency verified (no changes on second run)

Implementation Details:

Files to Modify:

• molecule/default/tasks/proxmox_test.yml - Replace placeholder assertions with real tests
• molecule/default/vars/proxmox_test_vars.yml - Test data for Proxmox scenarios

Dependencies:

• proxmoxer Python library for API testing
• kubernetes Python client.

Additional Notes:

Test should verify Proxmox API connectivity, validate VM lifecycle operations, check network interface configurations (PELI, QSFP templates), and ensure proper resource cleanup.
