feat: 养护模板/社区运营/体重趋势/计划日历 + 雪花ID重构 + 文件表与图片上传

后端 - 主键改雪花字符串 ID（pkg/idgen + Base.BeforeCreate），全表外键/JWT/中间件随之调整 - 新增 files 表：/api/upload 按 MD5 去重，返回 {id,url,md5}，服务端只收图片 - 头像/记录附图/帖子图改 file_id 关联，读取解析为 URL - 养护模板（物种×阶段）后台可配 + AI 生成草稿；建档按模板生成任务/计划/提醒 - 社区 AI 运营：虚拟账号池 + 每日定时/手动生成，帖子带 AI 标 - 计划路线图节点带真实日期；首页周历与计划日历同源；新增 day-plan 当日安排 - 体重趋势接口带备注；记录列表分页小程序 - 公共图片上传 utils/upload.js（仅图片）；记录拍照/我的头像/社区发图三处接入 - 首页日历点选查当日任务；记录页体重趋势可点看备注 + 时间轴分页折叠 - 计划页日历点选查当日计划；自定义 tabBar 高度调整后台（React） - 新增「养护模板」「社区运营」页；用户管理加机器人筛选 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
