fix(stats/self_input): 修复保存不入库/路由 404，补全部门与自媒体来源下拉

- 模型去掉 defaultSoftDelete=0，避免 ThinkPHP 软删过滤导致新增记录"隐形"
- 菜单 paths 改相对路径并新增「自录数据统计」目录，迁移已有菜单
- Lists/Overview 补部门关联、支持按部门筛选
- 数据权限改由 self_input_stats_view_all_roles 白名单 + DataScope 控制，
  编辑/删除完全交给按钮权限校验（移除"仅本人可改"硬限制）
- 新增 /stats.self_input/mediaSourceOptions 接口，统计页/账户消耗页/录入弹窗
  共用 useMediaSourceOptions + MediaSourceSelect，去重动态加载
