feat(t052): QEMU cluster comprehensive feature testing

T052 verifies all 8 PlasmaCloud services on the 3-node QEMU cluster:
- LightningSTOR: S3 API (SigV4 auth)
- FlashDNS: gRPC + DNS resolver
- NightLight: Prometheus-compatible metrics
- FiberLB: Load balancer gRPC API
- PrismNET: Virtual networking
- CreditService: Quota REST API
- K8sHost: Kubernetes API server
- PlasmaVMC: VM controller

All services verified running and responding.

Also adds VDE launch and recovery scripts for VM cluster management.
