fix: 修复评论/资料/导航胶囊/宠物档案/定位等多处问题，补全相关云函数

- 新增 addComment/getComments/getFollowList/followUser/getUser/updateProfile/updatePet/deletePet 云函数并完成部署
- 统一通过 app.globalData.navBarInfo 避让系统胶囊按钮（编辑资料/编辑宠物等页面保存按钮被遮挡问题）
- 编辑资料页所在城市改为省份 picker 选择
- 修复"我的"页动态为空（getUserPosts 应传 openid 而非数据库 _id）
- 重构编辑宠物页：品种改用 picker 滚轮（替代有数量上限的 actionSheet），标签改用 selectedTagSet 映射 + 自定义标签输入（5字以内、仅中英文/数字、最多8个）
- 接通宠物保存/删除真实云函数调用并同步本地缓存
- 移除 feed 页对不存在的 getStories 云函数调用，修复模拟器卡死
- 移除 post 页对不存在的 wx.reverseGeocoder API 的调用
- 统一扩展 AppGlobalData 类型并修正所有 getApp 调用的泛型，解决 TS 报错
