/**
 * AzureMessagingClient — HTTP-based messaging with Azure Container Instances.
 *
 * ACI containers expose an HTTPS FQDN. Axon uses:
 *   POST /message  → deliver a payload; response body is the result
 *   GET  /health   → liveness probe
 *
 * Security:
 *  - Only https:// endpoints are permitted
 *  - Private/internal IP ranges are blocked (prevents SSRF)
 *  - Response bodies are capped at 4 MiB
 *  - Prototype-polluting keys in remote JSON payloads are rejected
