Enforce HTTPS for all downloads to eliminate security vulnerabilities

- 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.
