feat(tab-bar): 重构底部导航栏支持多角色切换

- 新增医生和患者家属角色的 tab 配置
- 使用 v-for 动态渲染 tab 项，替代原有硬编码方式
- 根据用户角色动态切换 tab 内容和跳转路径
- 添加了角色为 2(医生)和 4(患者家属)的页面路径配置
- 优化 tab 跳转逻辑，统一通过 url 配置进行页面切换
- 增加了医生首页和家属首页的页面文件
- 更新 pages.json 添加新页面路径和 tabbar 配置
- 修复退出登录后未正确跳转至公共首页的问题
- 引入新的图标资源：设置和二维码扫描图标
- 移除了 tab 文本"用户"改为更具语义的"我的"
