Add system/homelab-deploy.nix module that automatically enables the listener on all hosts with vault.enable=true. Uses homelab.host.tier and homelab.host.role for NATS subject subscriptions. - Add homelab-deploy access to all host AppRole policies - Remove manual listener config from vaulttest01 (now handled by system module) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
