Subject: [PATCH] fix: change PP-OCRv5_server_det HPI backend priority to
 openvino-first

PP-OCRv5_server_det defaults to paddle_mkldnn backend when HPI is enabled
on cpu_x64, which causes std::exception crashes in multi-threaded serving
environments (gRPC, FastAPI workers, etc.) due to MKL-DNN thread-safety
issues.

This change swaps openvino before paddle_mkldnn in all cpu_x64 sections
(paddle30, paddle31, paddle311). GPU sections are unaffected.
