apollo_http_server: add configurable max_request_body_size as 5mb

[ArniStarkware]

Note

Low Risk
Small, localized config + routing change that only affects request size handling; main risk is inadvertently rejecting/allowing larger requests due to misconfiguration.

Overview
Adds a new static HTTP server config max_request_body_size (default 5MB) and exposes it through config dumping/schema and deployment app config templates.

Updates the Axum router so POST endpoints (/gateway/add_transaction and /gateway/add_rpc_transaction) enforce the configured request body limit via DefaultBodyLimit.

crates/apollo_http_server_config/src/config.rs line 15 at r2 (raw file):

// The value is chosen to be much larger than the transaction size limit as enforced by the Starknet
// protocol.
const DEFAULT_MAX_REQUEST_BODY_SIZE: usize = 5 * 1024 * 1024; // 5MB

This is not the constraint, right? As for now, transactions with proof can reach 6MB; we aim to lower it, but for the test env we need a larger margin.

Please add a check (or TODO here) when polling the dynamic config, that max_sierra_program_size > max_request_body_size and log a warning if it isn't.
