refactor(pages): 统一命名规范并修复 SeatMapOverlay 元素等待目标错误

- AutoLibPages → AutoLib（移除实现细节后缀）
- ReserveValidator → ReserveChecker（与 RecordChecker 命名一致）
- CaptchaHandler → CaptchaSolver（语义更准确，职责是"求解"验证码）
- ReserveChecker.validate() → check()（与 RecordChecker 风格统一）
- 修复 SeatMapOverlay.selectSeat() 中 _waitClickable 等待页面全局
  <a> 而非具体 seat_link 元素的时序缺陷
- ALMainWorkers 切换为 pages.AutoLib 新版实现
