Based on the 24.04 script with the following updates:
- Updated all version references from 24.04 to 26.04
- Fixed Tailscale APT repo from hardcoded 'jammy' to 'resolute' codename
(was a latent bug even on 24.04; jammy is 22.04)
- All other repos (Docker, Kopia, NodeSource) already use dynamic
VERSION_CODENAME detection and work as-is on 26.04
