feat(analyzers): add APIVoid v2 API support with v1 fallback

[Rohankaf]

Description

APIVoid released their v2 API on 10 Feb 2025, and v1 will be deprecated in Feb 2026.
IntelOwl was still using the v1 endpoints, so this PR updates the APIVoid analyzer to support the new v2 API.

What’s included

• Added full APIVoid v2 API support
• New JSON POST requests instead of GET
• X-API-Key header for authentication
• Updated endpoints:
  • /v2/ip-reputation
  • /v2/url-reputation
  • /v2/domain-reputation
• Added configuration option: "api_version": "v2" or "use_v2": true
• Preserved full backward compatibility with v1 (fallback on invalid or missing config)
