rust: broadcast OKX swaps through OKX's API, not our node RPC (match Go)

Previously execute_evm/execute_solana signed locally then broadcast via
the node (eth_sendRawTransaction / sendTransaction). Go broadcasts every
swap through OKX (Crypto/Okx:broadcastTransaction): OKX's node knows the
blockhash it embedded (no node-lag "Blockhash not found"), routes EVM txs
through a MEV-protected mempool, and lands Solana via its staked path.

- rest.rs: add authenticated POST (ApiKey::apply_post) — params in the
  JSON body, _key/_time/_nonce/_sign in the query, signed over
  POST\0path\0query\0sha256(body); send_bytes the exact hashed bytes.
- swap.rs: okx_broadcast_swap_tx (POST) + okx_await_order (orderStatus
  settlement poll) + new_quote_id. execute_evm now broadcasts via OKX
  (MEV per pref, no retry — re-signing burns the nonce) and confirms
  settlement so a revert isn't a phantom success. execute_solana
  broadcasts base58 (OKX base58-decodes; base64 silently fails to land),
  retries up to 3x with a fresh blockhash on retryable failures, confirms
  via orderStatus. Both return {chain, hash, orderId, quoteId}.
- handlers/swap.rs: thread MevProtection (opt-out, on by default) + an
  opaque QuoteId (caller-supplied or generated) into execute.

Tests updated to mock the OKX broadcast+orderStatus flow. 342 Rust tests
+ 64/64 Dart, 0 warnings. NOTE: the POST auth signature matches Go's
scheme but could not be validated against the live server here (mock
tests exercise the flow, not the real signature) — verify on first live
swap.
