feat: add wait mechanisms for delete and save operations in discrete material cleaner

This change adds robust wait mechanisms to prevent race conditions when
performing delete and save operations in the ERP system.

Changes:
- Add row number change detection after delete to confirm completion
- Add save button disappearance detection to confirm save completion
- Add row number range check (7000-8000) to skip specific rows
- Enable previously commented save button click
- Improve logging with detailed status messages
- Add timeout handling (10s for delete, 60s for save)
