fix(#681): 门诊收费点击已收费患者增加 encounterId 兜底

- 问题：已收费列表点击患者行时报错"参数[encounterId]要求类型为
  Long，但输入值为'undefined'"，导致右侧基本信息为空、收费项目一直 Loading
- 根因：row.encounterId 为 undefined 时直接拼入 URL，后端类型校验拒绝
- 修复：clickRow 加 encounterId ?? id 兜底；无 ID 时 msgError 提示并中止调用；
  同步写入 patientInfo.value 防止 handleClose/confirmCharge/changePayType 等
  后续路径再次读到 undefined
- 风格对齐 clinicrefund/index.vue、outpatientregistration/reprintDialog.vue
  已有的 encounterId || id 防御模式
- 编译：npm run build:dev ✓
