Add Proxmox inventory scripts and n8n sync workflow
- proxmox-inventory.sh: text inventory (RAM/CPU/Swap/Disk/IP/Gateway/Subnetz) - proxmox-inventory-json.sh: JSON variant with n8n webhook push, --vmids filter, --dry-run - n8n workflow: automated fact-sync between Proxmox and Outline docs, auto-creates pages for new VMIDs, ntfy summary notification - credentials (Outline/NTFY bearer tokens) intentionally excluded, see README
