root 6ea457d01d Add server security configs and setup script
- Nginx configs with security headers (X-Frame-Options, CSP, etc.)
- fail2ban jails for nginx (botsearch, bad-request, forbidden)
- Kernel hardening via sysctl (rp_filter, no redirects, log martians)
- SSH hardening (no root, max 3 attempts, no X11)
- UFW rules export
- Idempotent setup.sh to restore all configs on fresh install
- Flask bound to 127.0.0.1 (nginx-only access)
