修复多个bug并增强调试功能

修复的bug:
1. email_service.py: 验证码提取失败 - 从邮件Subject提取验证码(格式: XXX-XXX xAI confirmation code)
2. nsfw_service.py: enable_unhinged cookie错误 - sso-rw被错误设置为sso的值
3. grok.py: URL路径错误 - 分离base_url和site_url,修复重复/sign-up
4. api_solver.py: Turnstile JS语法错误 - return语句在全局作用域非法,包装为IIFE

增强功能:
- 添加详细调试日志,便于定位问题
- 改进Turnstile solver等待逻辑,检测API可用性
- 添加更多错误处理和状态输出
