refactor(P1): 5 项代码质量改进 — 消除重复、拆分巨型组件、统一基础设施

Task 4: 统一 amap.ts 为完整 API 客户端
- 扩展 amap.ts 为统一客户端（amapFetch 8s 超时 + 错误处理）
- 导出 searchPlaceText/searchPlaceAround/getInputTips/reverseGeocode/getTransitDirection
- 精简 4 个 location route 为单行调用，blindboxPlanGen 删除 ~80 行内联 API 代码

Task 2: 抽取 ShareCardShell 消除三兄弟重复
- 新建 ShareCardShell.tsx 共享外框/背景/品牌头/QR 底部
- RestaurantShareCard 406→268 行，BlindboxShareCard 341→173 行，BlindboxPlanShareCard 277→159 行

Task 3: 拆分 BlindboxPlan.tsx (742→371 行)
- 提取 planUtils.ts (guessCategory + formatDuration)
- 提取 PoiSearchField / SortablePlanItem / PlanItemEditModal 三个独立组件

Task 1: 拆分 blindbox/[code]/page.tsx 上帝组件 (1300→509 行)
- 提取 useBlindboxRoom / useBlindboxIdeas / useBlindboxPlan / useBlindboxDraw 四个 hooks
- 提取 BlindboxPoolPhase / BlindboxRevealPhase 两个子组件
- 主页面仅保留 phase 协调 + hook 组装 + 子组件渲染

Task 5: 统一 SWR 数据获取层
- 新建 fetcher.ts (FetchError 携带 status，401 不重试)
- 新建 useBlindboxRooms / useAchievements / useFavorites SWR hooks
- useRoomPolling 改用共享 fetcher
- blindbox 大厅/成就/个人中心页面删除手写 fetch 样板代码
- JWT 过期时自动弹出登录框而非反复重试
