♻️ refactor: 统一图片渲染架构并引入通用UI组件系统

🎨 **渲染服务重构**
- 统一图片渲染入口，引入主题系统支持
- 优化Jinja2环境管理，支持主题覆盖和插件命名空间
- 新增UI缓存机制和主题重载功能

✨ **通用UI组件系统**
- 新增 zhenxun.ui 模块，提供数据模型和构建器
- 引入BaseBuilder基类，支持链式调用
- 新增多种UI构建器：InfoCard, Markdown, Table, Chart, Layout等
- 新增通用组件：Divider, Badge, ProgressBar, UserInfoBlock

🔄 **插件迁移**
- 迁移9个内置插件至新渲染系统
- 移除各插件中分散的图片生成工具
- 优化数据处理和渲染逻辑

💥 **Breaking Changes**
- 移除旧的图片渲染接口和模板路径
- TEMPLATE_PATH 更名为 THEMES_PATH
- 插件需适配新的RendererService和zhenxun.ui模块
