🔧 Fix: Comprehensive GitHub token integration for all Docker workflows

✨ Complete GitHub Token Support:
- Add github-token parameter to all Trivy actions (security + release)
- Add GITHUB_TOKEN environment variable to all Docker build steps
- Add global GITHUB_TOKEN environment to CI and release workflows
- Ensure consistent token usage across all workflow jobs

🐳 Docker Workflow Improvements:
- CI workflow: Docker build with GitHub token for base image pulls
- Security workflow: Docker build + Trivy scans with token
- Release workflow: Docker build + security scans with token
- Better authentication for all container operations

 Authentication Benefits:
- Eliminates GitHub API rate limiting issues
- Fixes 'Bad credentials' errors in Trivy scans
- Improves reliability of Docker base image pulls
- Ensures consistent authentication across all workflows

 Affected Workflows:
- CI/CD Pipeline: Enhanced Docker builds
- Security Scans: Fixed Trivy authentication
- Release Pipeline: Complete token integration
