feat: 盲盒房间体系重构 — 强制登录、独立房间、用户归属

- 新增 BlindBoxRoom/BlindBoxMember 模型，BlindBoxIdea 增加 userId/drawnById
- 新增房间 API（创建/加入/列表/详情），所有盲盒 API 增加认证和成员校验
- 新建盲盒大厅页面（三层引导式设计：未登录氛围页/首次创建引导/房间列表）
- 新建盲盒房间页面（成员校验/邀请分享/用户归属展示/自动聚焦）
- 首页删除契约画廊和 localStorage 盲盒逻辑，周末契约跳转到 /blindbox
- 清理旧路由 /room/[id]/blindbox
- 提取共享工具 src/lib/blindbox.ts（错误响应/房间号生成/成员校验）
- AuthModal 支持 defaultTab 参数
- 更新项目规范：新项目原则、代码优雅和复用优先
