fix: 修复多个关键问题

- 修复前端路由守卫：未登录时不显示提示，直接跳转登录页 - 修复API拦截器：401错误不显示提示，直接跳转 - 增强验证码显示：图片尺寸从120x40增加到200x80 - 增大验证码字体：从28号增加到48号 - 优化验证码字符：排除易混淆的0和1 - 减少干扰线：从5条减少到3条，添加背景色优化 - 增强登录API日志：添加详细的调试日志 - 增强验证码生成和验证日志 - 优化异常处理和错误追踪影响文件： - src/router/index.ts - src/api/request.ts - app/services/auth_service.py - app/api/v1/auth.py - app/schemas/user.py 测试状态： - 前端构建通过 - 后端语法检查通过 - 验证码显示效果优化完成 Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
