Add /how-to-register documentation page with registration workflows

[Copilot]

Adds a dedicated page at /maia/how-to-register documenting user and project registration workflows with visual guides.

Changes

• New route: apps/home/urls.py adds how-to-register path
• View: apps/home/views.py implements how_to_register()
• Template: apps/templates/home/how-to-register.html provides:
  • User registration workflow (navigate → fill form → email verification)
  • Project registration workflow (access form → resource allocation → submission)
  • Visual form screenshots for both flows
  • Troubleshooting section (common errors, validation formats)
• Assets: Form screenshots at apps/maia/static/assets/img/MAIA/registration-*.png

Implementation notes

• Uses Django URL reversal ({% url 'register' %}) for all internal links
• No inline JavaScript to maintain CSP compliance
• Follows existing dashboard styling patterns

Screenshot

Page includes step-by-step instructions for both registration types, annotated screenshots, and direct links to registration forms.
