New Signal Review/Action Column

1. Added 8_WC_signal_review.R, a new script that:

• Processes the results and signal report files.
• Generates a deduplicated list of all new World Cup signals identified to date.
• Creates an output spreadsheet with a dedicated column for analysts to record signal classifications and review outcomes. Goal is to keep notes as you go for a final summary report of how TreeScan was used and impacted WC PH response.

2. Updated run_full_pipeline.R to automatically execute 8_WC_signal_review.R as part of the standard workflow.

• The signal review spreadsheet is now regenerated and updated automatically whenever new signals requiring investigation are identified during daily analyses.
• Based on original script by Alison Levin-Rector (NYC DOHMH)
