feat: Add wildcard trusted origins for cannaiq.co and cannabrands.app

Add *.cannaiq.co and *.cannabrands.app patterns to both:
- auth/middleware.ts (admin routes)
- public-api.ts (consumer /api/v1/* routes)

This allows any subdomain of these domains to access the API without
requiring an API key.
