Fix deployment issues: Add db:seed to setup, fix DatabaseSeeder, add production guide

CRITICAL FIXES:
- DatabaseSeeder now calls RolePermissionSeeder to create roles, permissions, and admin user
- setup.sh and setup.bat now run db:seed automatically during setup
- Created PRODUCTION_DEPLOYMENT.md with complete production deployment guide
- Removed duplicate admin user creation from setup scripts

This ensures:
- Admin user (admin@example.com / password) is created automatically
- Roles (admin, editor, viewer) are created during setup
- Permissions are seeded properly
- Production deployments have clear step-by-step instructions
- PHP Redis extension installation documented
- All common deployment issues addressed

The 2-minute setup now truly works out of the box.
