  - Changed from 'grep || tail' fallback to 'sed | grep' pipeline
  - Properly strips 'Digest: ' prefix before extracting hash
  - Prevents corrupted hash format that caused Authelia crash loop

- setup-homelab.sh: Fix automatic deployment call
  - Added 'sudo' when running deploy script from setup
  - Prevents 'Please run as root' error during automatic deployment
