Replace grid layout with tree diagram:
Modem → Firewall → Switch → 3 Proxmox servers → VMs/CTs
- Services.yaml restructured with parent/type fields
from real Proxmox API data (TYAN CAS, Cisco1, DellT430-2)
- NetworkGraph renders vertical hierarchy with branch lines
- ProxmoxColumn shows server card + VM pills grid
- Compact VmPill for VMs/CTs (status dot + name + last octet)
- InfraCard for physical infrastructure nodes
- Other devices section at bottom (AP, printer, iDRACs, PCs)
- Added type/parent fields to NetworkNode TypeScript interface
