Add shared services infrastructure for cross-host data

Browse source 
Created centralized service definitions in shared/services.nix to store
service metadata (domains, IPs, ports) that need to be accessible across
multiple hosts. This replaces the per-service split DNS module approach
with a single source of truth.

Services are now exported through utils.nix for easy access in host configs.
