feat: 完善后端并新增 Vue3 WebUI

后端:
- 修复登录校验、DB 并发(单例+WAL+纯Go sqlite)、会话密钥持久化等核心缺陷
- 新增 Timer CRUD/签到/手动触发、执行日志、仪表盘、驱动元数据等 API
- 统一驱动接口: 带 context 的执行器、真实错误返回、敏感字段掩码、连通性测试
- 补全钉钉执行器; Timer 触发/提醒去重; 配置支持默认值与环境变量覆盖

前端:
- Vite+Vue3+TS+Pinia+Element Plus, 由驱动元数据动态渲染配置表单
- 登录/仪表盘(倒计时环)/定时器/规则/账号/日志/设置页面, 支持暗色模式
- 主题色 #66ccff, 信号波纹 logo, go:embed 单二进制部署

构建: Dockerfile 增加前端构建阶段; 补充各驱动配置文档
