chore(reports): remove outdated npm log analysis reports

Delete historical Nginx Proxy Manager log analysis outputs from
app/reports/npm, including generated report snapshots and the
associated data artifacts (ips.json, requests.csv, error_paths.csv,
host_summary.csv, ua_summary.csv, scanner/blocked IP lists, and the
MikroTik block script). These files are regenerated on demand and no
longer need to be tracked.
