fix: resolve #407 examination request wrong advice type classification

Bug #407: 检查申请同步到医嘱列表时，医嘱类型被错误标注为中成药而非诊疗

Root cause: ServiceRequest.categoryEnum was not set when creating service requests from examination applications, causing the system to misclassify them as Chinese medicine (adviceType=2) instead of medical treatment (adviceType=3)

Fix: Added serviceRequest.setCategoryEnum(3) in both POST and PUT methods of ExamApplyController to correctly classify examination requests as medical treatment type

Impact: Examination requests will now display correct type (诊疗/medical treatment) in the advice list and won't trigger database errors when signing
