Fix: Remove leftover git merge conflict marker from cwa_schema.sql

Resolves SQL syntax error: near '>>': syntax error

The merge conflict marker '>>>>>>> origin/main' at line 95 was causing:
- cwa-update-notification-service failures
- translation-notification-service failures
- ingest_processor crashes
- All services depending on CWA_DB initialization to fail

This was missed during the merge conflict resolution in commit 646544b.
