Remove debug logging from ticket linking function

The ticket propagation issues have been resolved. Debug logging
is no longer needed in production code.

Changes:
- Removed AuditLog debug logging from link_open_internal_tickets_to_run
- Preserved debug logging code in backupchecks-system.md for future use
- Updated changelog to document removal

The debug code is available in the technical documentation if
troubleshooting is needed again in the future.

 - Fixed Run Checks popup showing resolved tickets for runs where they were never linked by replacing date-based ticket/remark queries in `/api/job-runs/<run_id>/alerts` endpoint with explicit link-based queries (now only shows tickets/remarks that were actually linked to the specific run via ticket_job_runs/remark_job_runs tables, completing the transition from date-based to explicit-link ticket system)
 
 ### Changed
-- Added debug logging to ticket linking function to troubleshoot resolved ticket propagation issues (writes to AuditLog table with event_type "ticket_link_debug", visible on Logging page, logs EVERY run import to show whether tickets were found and their resolved_at status, uses commit instead of flush to ensure persistence)
 - Reduced test email generation from 3 emails per status to 1 email per status for simpler testing (each button now creates exactly 1 test mail instead of 3)
 
+### Removed
+- Removed debug logging from ticket linking function as ticket propagation issues are now resolved (debug logging code preserved in backupchecks-system.md for future troubleshooting if needed)
