feat: 公共表更名 common/member 前缀 + 插件命令自动加载 + 版本 1.1.1

- 18 张公共表更名（addon/attachment/configure/links/spider_log/spider_stat/sms/notice/ad/task/prop/medal/help/card -> common_*，member_wallets->member_wallet，score_rule/score_log -> member_*，addon_config->common_addonconf），模型全部对齐新表名，Db 直引用清零
- Attachment 模型补  表名绑定，修复富文本上传查 wxapp_attachment 1146 隐患
- install.sql + 迁移 SQL：backend_admin/backend_role delete_at 默认 0，修复软删除(NULL != 0)误过滤导致后台菜单为空
- AppService::boot() 支持插件 info.php 声明 commands 自动注册插件命令（psr-4 自动加载，坏类名自动跳过）
- 各插件（haonav/mqttbroker/wxchat/articles/blog/forum 等）字段与配置同步调整
- 框架版本 1.1.0 -> 1.1.1
