feat: 每日任务顺延与增删改 + 计划到期续期 + 靠谱养护模板 + 图片URL修复

后端
- 每日任务惰性生成：某天为空则从最近一天顺延复制（done 重置），首天用模板
- 任务增删改 API（POST /pets/:id/tasks、PUT/DELETE /tasks/:id），改动自动顺延
- 30 天计划到期自动归档并按当前阶段生成新一轮
- 内置养护模板重写为兽医常识向：狗每阶段含遛狗/牵引/狂犬，猫含猫砂/梳毛/饮水
- 文件 URL 改为按 object_name + 当前配置动态拼接，换 IP/域名不再有旧地址

小程序
- 首页今日任务加「管理」入口：增删改任务弹层
- 记录时间轴显示照片缩略图（可全屏预览）+ 拍照成功提示
- 社区发布条精简为单个「发布图文」按钮，去掉头像/输入框误触
