Add storage flow & HA analysis diagram

Browse Source 
Graphviz DOT-based diagram showing the complete storage path:
App pods → PVCs (StorageClass/Retain-Policy) → Longhorn replicas →
K3s worker nodes → Proxmox hosts.

HA analysis annotated with color coding:
- Red: SPOF (control-plane on n01, share-manager on n01)
- Orange: Degraded on failure (CSI controllers on n02, RWX volumes)
- Green: HA covered (2 Longhorn replicas on different Proxmox hosts)
