Title

Add Azure Container Instances (ACI) support

Description

Implement Azure Container Instances support inside floci-az.

The purpose is to run real Docker containers per container group and report their state, IP, and logs through the ARM control plane — the Azure counterpart of AWS ECS / Fargate, and a building block for Container Apps.

ARM provider: Microsoft.ContainerInstance/containerGroups. Each container group maps to one or more real local Docker containers; the handler surfaces instanceView, restart policy, ports/IP, and containerLogs.

Suggested capabilities:

• Container group CRUD (ARM)
• Launch real Docker containers (image from imageReference, env, ports, resources)
• Power/state reporting via instanceView (Running / Terminated / Waiting)
• GET .../containers/{name}/logs (container logs)
• restart / stop / start group actions

floci-az notes: reuse the aks / vm container lifecycle — go through ContainerBuilder + ContainerLifecycleManager, never call dockerClient directly; Docker failures must degrade gracefully (non-fatal).
