laoyang 55d2dfa46b 后台管理界面:软件/分类/状态可配,反馈可改挂归属 (#1)
## 新增 lib/admin_taxonomy.php
- 软件:增删改、排序、启停;新增时自动预置 Bug/功能建议/其他 三个分类
- 分类:在选定软件下增删改、排序、启停
- 状态:改名、改「给用户看的话」、排序、启停;标识不可改(历史数据靠它对应)
- 反馈改挂:th_move,可把反馈移到别的软件/分类,跨软件的非法分类会被拒

## 安全与边界
- 所有动作走 CSRF 校验(沿用现有机制)
- 不能删最后一个软件 / 没有分类的软件至少要留一个启用分类
- 有反馈挂着的软件或分类不能删,提示改为停用(停用后前台消失、数据保留)
- th_move 加入 fb_admin_is_taxonomy_act 白名单,否则会被「问题不存在」静默吞掉

## admin.php 接线
- 引入模块 + 动作分发 + tab 白名单加 taxonomy/statuses + 导航两项
- 前置检查放行不依赖 $t 的动作(否则新增软件报「问题不存在」)
- 全部问题列表:加软件筛选、分类跟着软件走;修掉三处仍在用旧
  fb_statuses()/fb_categories() 的遍历(那会渲染出错)
- 详情页加「归属」表单,软件徽章可显示

## 其他文件
- api.php:状态/分类改数据库;新增 ?sw= / ?software_id= / ?cid= 过滤,
  老的 ?category=<slug> 仍可用(在所属软件内解析)
- thread.php:详情页显示软件与分类徽章
- config.example.php:移除 categories / statuses,改由数据库管理

## 修掉两个真实 bug
1. 移除配置后出厂分类兜底只剩 4 个,漏了「同步问题」—— 建库后核对数量才发现
2. th_move 不在白名单,POST 后返回 200 却静默不生效

验证:后台 e2e 29/29;改挂与联动 13/13;PHP 8.5 全部入口 0 弃用;
19 个 PHP 文件语法全过。
