复查修复(二): 同步模块与安全遗留

- 修复 remove_sync_source 引入的 stop_sync KeyError 回归(容错 get)
- stop_sync 不再删除存活线程条目(防双 worker);FTP 子目录递归传真名(不再 KeyError)
- 远程文件名统一 _safe_remote_name 校验(FTP/SFTP/HTTP 防路径穿越)
- temp 任务名加随机后缀防碰撞;temp 状态/线程完成后清理(防 sync_state.json 膨胀)
- save_sync_state 快照+原子写(临时文件+os.replace),持锁调用不死锁
- URL 打印脱敏(user:pass@ -> ***@)
- _need_sync_http size=0 不再全量重下(仅按存在性)
- cron 同一分钟去重;PyPI 进度只更新当前源
- v2 start_sync 不再把 bool 当 task_id
- UserRecord.to_dict 脱敏(不返回 password_hash/token),新增 to_dict_private/get_user_with_password
- config_hotreload 单配置源(set+persist 与热重载一致);server.py 用 get_all()
- 会话创建时顺带清理过期项;JSON stats/历史读改写加锁
- 解压目标目录先校验;FTP RETR 命令注入防护;rsync --delete 目标保护
- git/urlopen 补超时;cleanup_completed_tasks 删旧留新
