refactor: 移除 AI 词云、AI 时间轴和博客模块

暂停开发以下功能，将设计文档移至未完成计划文件夹：

- AI 词云 (Keyword Cloud): 前端、API、数据库模型、n8n 工作流
- AI 时间轴 (AI Timeline): 前端、API、数据库模型
- 博客 (Blog): 导航链接占位

变更内容：
- 删除词云和时间轴的前端页面及组件
- 删除 /api/keyword-cloud/* 和 /api/events/* API 端点
- 从 prisma/schema.prisma 移除 Keyword, Quarter, VisualStyleRule, KeywordCloudErrorLog, AIEvent 模型
- 从 validations.ts 移除相关 Zod Schema
- 从国际化消息中移除 keywordCloud/timeline 命名空间
- 从导航菜单移除词云、时间轴、博客链接
- 更新 CLAUDE.md 移除词云系统文档

设计文档已移至 .omc/plans/postponed-features/ 供后续恢复开发参考
