style(sponsor/PersonDetail): 对齐 executor/PersonDetail 风格

- 加 page-card 包裹 + breadcrumb 三级 '首页 / 人员管理 / 人员详情'
- detail-card → form-card nested (跟 NewPerson 一致)
- detail-actions → form-actions
- max-width: 1000px → 1200px
- 删 :deep(.el-button) { border-radius } (skill 禁忌覆盖 el 默认主题)
- 删 :deep(.el-form-item__label) 颜色覆盖 (让 el 默认)
