feat: 全面公告系统 + 全系统 Bug 修复

全面公告系统： - notifications 表新增置顶/强提醒/定时发布/过期/配图/链接字段 - 后端增强：7 个接口（列表/置顶/未读数/已读/发布/编辑/删除） - 首页强提醒公告弹窗 - 通知中心：置顶标记、配图展示、链接跳转、管理员操作 - 管理员发布表单：标题+内容+链接+配图+置顶+强提醒+定时+过期 Bug 修复： - 401 重试队列竞态导致请求永久挂起 - 多分类筛选条件被静默丢弃 - 网络错误导致群组选择丢失 - Numpad 输入 '.' 显示异常 - transaction store 错误时清空数据 - 首页/预算页 Promise.all 部分失败阻塞关键数据 - CSS prefers-reduced-motion 类名不匹配 - 通知 read-all 遗漏群组通知 - auth.ts 错误日志缺少 stack trace - stats 页面 v-for key 使用 index - add 页面重复调用 fetchCategories
