PR Summary

Low Risk
Refactor-only: same middleware layers and order as before; risk is limited to accidental drift if future edits miss updating the macro or call-site imports.

Overview
Unifies the JSON-RPC HTTP middleware stack so plain HTTP (start_server) and HTTPS (tls::start_tls_server) share one definition instead of two copy-pasted ServiceBuilder chains.

Adds prover_http_middleware! in server.rs (placed above pub mod tls so tls.rs can expand it) and wires both transports to prover_http_middleware!(cors_layer, ohttp_layer). Inline layer-order comments at the call sites are replaced with pointers to the macro docs, which now hold the full rationale (health outermost, OHTTP outside compression, body mapping for HttpBody).
