1. 修复 handle_change 中 `or` 应为 `and` 的逻辑错误（api.py）
   - `path != "" or path is not None` 恒为 True，导致未传递的参数
     以 None/空值覆盖已有的有效配置

2. 修复 DefaultRefer.__init__ 忽略构造函数参数（api.py）
   - 构造函数声明了 path/text/language 参数但未使用，直接引用
     全局 args 变量，导致类无法正确复用

3. 修复 GET /tts 端点参数为 None 时 AttributeError（api_v2.py）
   - text_lang 和 prompt_lang 默认值为 None，未提供时直接调用
     None.lower() 导致崩溃

4. 替换 eval() 为安全的字符串比较（inference_webui.py）
   - eval() 会执行任意代码，当环境变量被恶意设置时存在代码
     注入风险，改用安全的字符串比较
