fix: How It Works rendering - icon template overflow + 3-step cap

- Fix icon template index overflow: stepIconTemplates[i] -> modulo cycle
  through 3 templates for commands with more than 3 steps
- Cap prepare-delivery to 3 steps (was 5, too wide for row layout)
- Add flex-wrap to desktop steps layout as safety net
