feat(bazi): 八字页重构——空态示例排盘+字段术语表+文化声明，生辰档案绑定

- 八字页：未绑定生辰时展示虚构示例排盘(1990-08-08 10:30男)与15条字段说明，
  附传统文化声明文案；已绑定时支持多档案切换，排盘增强(十神/藏干/纳音/五行配色/命盘概览)
- 个人中心：新增生辰管理卡片，每用户免费绑定3个出生年月；登录改为真实微信登录
- 服务端：新增 BirthProfile 模型与 /api/user/birth-profiles 增删查接口，AutoMigrate 建表
- 前端：新增 birth-profile.js 本地存储优先+登录后云端双向同步
- 修复：个人中心 tabBar 页面入口误用 navigateTo 改为 switchTab
