Security headers are now disabled by default since most deployments use a reverse proxy (Traefik, Nginx) that already adds these headers. Enable with SECURITY_HEADERS_ENABLED=true for direct deployments.
Changes:
- Set security_headers_enabled default to False in app/config.py
- Update all documentation to reflect new default
- Comment out examples in .env.demo (now showing disabled state)
- Update SECURITY_AUDIT.md to reflect reverse proxy as default deployment
- Tests still pass (3 passed, 8 skipped as expected with headers disabled)
