feat: implement task list updates

- getting-started.md: Moved checklist before Simple Setup, removed Round 4 section
- authelia-customization.md: Updated Authentik reference to alternatives stack
- services-overview.md: Added clickable links to all stack compose files
- setup-homelab.sh: Added prompt to run deployment script after setup (defaults to yes)
- traefik.yml: Changed default to DNS challenge for wildcard certificates (DuckDNS)

All documentation now reflects wildcard certificate usage with DNS challenge.
