fix: add log directory ownership check to pre_deploy.sh

Per review feedback: ensure logs directory is owned by www-data
during deployment, preventing silent fallback to console-only logging.

The pre-deploy script now:
- Checks if logs directory has correct ownership
- Automatically fixes ownership if possible (when run as root)
- Fails deployment if ownership cannot be fixed
