Replace Molecule Redfish component placeholder assertions with real tests

User Story:

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

Problem Statement:

Redfish component tests don't validate hardware management operations, power control, or vendor-specific implementations (HPE iLO, Dell iDRAC).

Acceptance Criteria:

• Redfish CRD creation validated with correct configuration
• Hardware discovery and inventory verified
• Power operations tested (on/off/reset)
• Boot order configuration validated
• Vendor detection working (HPE, Dell, Supermicro).
• IPMI fallback functionality tested
• Idempotency verified (no changes on second run)

Implementation Details:

Files to Modify:

• molecule/default/tasks/redfish_test.yml - Replace placeholder assertions with real tests
• molecule/default/vars/redfish_test_vars.yml - Test data for different hardware vendors

Dependencies:

• python-redfish library (sushy)
• pyghmi for IPMI testing.
• kubernetes Python client

Additional Notes:

Test should validate Redfish API connectivity, verify hardware information retrieval, test power state management, and ensure compatibility with different BMC implementations.
