Task: Fix Screenshot Update Issue

Context

The user reports that in the "Suivi prix" (Tracking) section, triggering an update ("Mise à jour") does not update the screenshot. This has been identified as a caching issue due to static filenames.

Current Focus

Implementing logic to generate unique timestamped filenames for screenshots to bypass browser caching and ensure the latest image is displayed.

Master Plan

• Modify tracking_scraper_service.py to use timestamped filenames for tracking screenshots
• Verify that item_service.py correctly picks up the new files
• Create verification script verify_screenshot_update.py
• Run verification and confirm fix
• Modify ItemService.get_items to scan filesystem for latest screenshot
• Update ItemService.delete_item to clean up all related screenshots
• Create verify_fix_item_service.py to test the new logic

Current Focus

Improving price extraction reliability for B&M Stores and others.

• Analyze ai_schema.py to check the extraction prompt
• Improve ScraperService._extract_text to be more targeted (e.g. main content only)
• Update AI prompt to better handle multiple prices (unit vs package)
• Verify extraction logic with simulation script

Progress Log

• Identified the issue: ScraperService overwrites item_{id}.png.
• Created implementation plan.
• User approved plan.
• Implemented filesystem scanning in ItemService.
• Verified fix with verify_fix_item_service.py successfully.
• Improved AI prompt to ignore unit prices (like "Prix au litre").
• Enhanced text extraction to remove menu/footer noise.
• Verified logic with verify_extraction_logic.py (simulated).
