refactor: optimize performance and code quality with significant improvements

Performance optimizations:
- Pre-load database materials into HashSet (O(1) lookup) instead of O(n) per material query
- Add 60s safety timeout on loading waits to prevent deadlocks
- Simplify navigation loop with while True pattern

Code quality improvements:
- Replace print-based logging with proper logging module
- Add _get_input_value() helper to reduce duplication
- Move all imports to top of file (re, time, TimeoutError)
- Remove redundant docstrings and consolidate logic
- Add detailed module docstring explaining optimizations

Bug fixes:
- Fix iframe variable naming conflicts (detail_main_frame, detail_inner_frame)
- Add error handling for individual order processing failures
- Simplify setup_query_interface() logic
- Change password to placeholder for security

 """
 离散备料计划维护数据清理工具
-负责登录、逐个清理订单数据
+功能：自动登录 ERP 系统，根据负责人姓名批量清理指定的备料计划物料。
+优化点：
+1. 数据库预取：从 $O(n)$ 次数据库查询优化为 $O(1)$ 内存匹配（HashSet）。
+2. 日志规范：使用 logging 模块替代 print。
+3. 代码整洁：移除方法内导入，增加通用定位辅助函数。
