Enforce HTTPS for all downloads to eliminate security vulnerabilities

Browse Source 
- Convert 16 HTTP URLs to HTTPS across 3 critical scripts
- Dell OMSA script: Ubuntu archive and Dell repository URLs now use HTTPS
- Proxmox legacy script: Download URLs converted to secure connections
- SSL stack script: Apache source URLs updated to official archive
- Update documentation to reflect resolved security issues
- Mark HTTPS enforcement as completed in todo lists

This addresses the second critical security concern from the security review,
eliminating man-in-the-middle attack vectors during package downloads.

## Risk Assessment 📊 ## Risk Assessment 📊
**Overall Risk Level:** Medium-Low **Overall Risk Level:** Low-Medium ⬇️ (Reduced from Medium-Low)
The repository contains well-architected defensive security tools with strong error handling and modular design. However, the deployment methodology and some insecure download practices present moderate security risks that should be addressed before production use in high-security environments. The repository contains well-architected defensive security tools with strong error handling and modular design. **Major security improvement:** The insecure `curl | bash` deployment method has been replaced with git-based deployment. Remaining concerns are primarily around hardening the provisioning scripts themselves rather than the deployment method.
**Recommendation:** Address high-priority security issues before deploying to production systems. The codebase foundation is solid and requires primarily operational security improvements rather than architectural changes. **Recommendation:** Continue addressing remaining security issues (HTTPS enforcement, secrets management) but the critical deployment risk has been mitigated. The codebase is much safer for production use.
## Update Summary (July 14, 2025)
**✅ Resolved Issues:**
- Insecure deployment method replaced with git clone approach
- README.md updated with project management and community links
- Deployment security risk significantly reduced
- All HTTP URLs converted to HTTPS (Dell OMSA, Proxmox, Apache sources)
**🔄 Remaining Priorities:**
1. ~~HTTPS enforcement for internal downloads~~ ✅ **RESOLVED:** All HTTP URLs converted to HTTPS
2. Secrets management implementation
3. Script integrity verification
4. SSH key rotation from repository
