ansible: drop dead caddy_ansible dep + commented-out ns/netbox/tailscale_home plays

caddy_ansible.caddy_ansible was only referenced by the (commented) netbox play,
so removing the disabled play also makes the role unused. ns play was already
superseded by the BIND9 play. Tailscale-on-home-hosts was never re-enabled
post-Talos-migration — drop the stub; restore from git history if needed.
