refactor(submissions): 方案A — mapper submitter_name + 页面样式对齐 + 紧急迁移

- mapper: selectFields 加 COALESCE(bp.name, u.user_name), LEFT JOIN biz_person (uk_person_user_id 防笛卡尔积)
- mapper: insert 补 7 字段 (plan_name/plan_direction/plan_category/project_form/design_file_url/is_settled/project_no), plan_name NOT NULL 缺默认
- SQL: 紧急迁移脚本 add submitter_id + idx + biz_person UNIQUE (ALTER, 不 DROP)
- SubmissionNew: page-card + breadcrumb + max-width 1200px, accept=.pdf/.png/.jpg/.jpeg, __silentError 防双 toast
- SubmissionNew: el-upload drag 模式 A (对齐 Meetings.vue, 删 design-uploader 自定义 CSS)
- SubmissionDetail: 删状态/投稿人/投稿时间/审计, 改 Preview 组件展示设计文件
