feat: 合并 admin/manager 重复页 + 公示意向 + 劳务签署

页合并 (admin/manager 共用, route.path 角色感知):
- expert: Experts.vue + ExpertNew.vue (list/new/edit/view 一套)
- sponsor-orgs: SponsorOrgs.vue
- sponsor-people: SponsorPeople.vue + SponsorPersonNew.vue + SponsorPersonDetail.vue
- executor-orgs: ExecutorOrgs.vue
- executor-people: ExecutorPeople.vue + ExecutorPersonNew.vue + ExecutorPersonDetail.vue
- 给 SponsorPeople / ExecutorPeople op 列补上 查看/编辑 按钮 (潜在 bug 修复)
- 详情弹窗统一用 el-descriptions 风格 (替代 admin 旧版 ElMessageBox.alert)

后端:
- BizSignController + BizSignServiceImpl + PdfService (劳务签署 PDF 流程)
- BizPublicityIntentController (公示意向: 支持/执行)
- BizPublicitySupportIntent / BizPublicityExecutionIntent ExportVo
- BizMeetingAttendee 字段合并 (bank_region 替代 bankProvince/bankCity)
- BizExpert 字段合并 (id_card_attachments CSV, bank_region)
- Excel 导入模板精简 (开户行 1 列)

前端:
- doctor/SignFill + SignContract + SignSuccess (劳务签署 3 页流程)
- ImportResultDialog 通用组件
- IdCardUploader 重构 (单 v-model:idCardAttachments, CSV 格式)
- AreaCascader 调整
- Login.vue + AdminLayout.vue + PortalShell.vue + Home.vue 适配

DB: 字段合并 (id_card_front/back → id_card_attachments, bank_province/city → bank_region)
