Fix CSRF 403 error: add X-Forwarded-Host header to Nginx and update CSRF_TRUSTED_ORIGINS

- Created nginx-smartsoltech-fixed.conf with proper SSL and CSRF support - Preserved existing SSL certificates from /etc/letsencrypt/live/www.smartsoltech.kr/ - Added X-Forwarded-Host header (critical for Django CSRF validation) - Fixed location block order (static/media before /) - Implemented proper HTTP→HTTPS and www→non-www redirects - Updated CSRF_FIX.md with comprehensive troubleshooting guide
