gitea 920b69cfca feat: plug-and-play refactor — docker-npm action, CF support, whitelist live-update
- Replace iptables-allports with docker-npm action (DOCKER-USER + xt_string
  X-Forwarded-For matching + INPUT chain) matching user's working setup
- Add telegram_notif.sh (deployed to /data/action.d/ at first run, user-editable)
- Add cloudflare.conf action; jail.cloudflare.local enabled via CF compose file
- Two compose files: docker-compose.yml (standard) and docker-compose.cloudflare.yml
- entrypoint: modprobe xt_string, DOCKER-USER chain check, CF jail auto-selection,
  telegram_notif.sh deployment to persistent volume on first run
- Fix whitelist live-update: addignoreip/delignoreip called alongside jail.local write
- Hardcode AUTOBAN_THR=75 and DEFAULT_DAYS=3 (remove env vars)
- Include Nginx Proxy Manager in both compose files with shared log bind mount
- Rewrite filters for actual NPM log format ([Client <HOST>] real IP extraction)
- Add DATA_DIR, Telegram, CF API key fields to .env.example
