refactor(proxy): preserve original header wire order and add non-streaming body timeout

- Rewrite build_raw_request to emit headers in original
  client-sent sequence instead of hash-map order
- Remove unused OriginalHeaderCases::get_all method
- Add body_timeout to read_decoded_body to prevent
  requests hanging when upstream stalls after headers
