/**
 * AkashMessagingClient — HTTP-based messaging with Akash container deployments.
 *
 * Akash workloads run as Docker containers. AxonSDK containers expose a small
 * HTTP API on their lease URL:
 *
 *   GET  /health   → liveness probe (returns 200 "ok")
 *   POST /message  → deliver a payload; response body is the result
 *
 * The `processorId` for Akash is the full lease endpoint URL, e.g.:
 *   https://provider.akash.network:31234
 *
 * Security:
 *  - Only https:// endpoints are permitted (enforced in assertSafeAkashEndpoint)
 *  - Private/internal IP ranges are blocked (prevents SSRF)
 *  - Response bodies are capped at 1 MiB
 *  - Prototype-polluting keys in remote JSON payloads are rejected
