fix: Improve API initialization with lazy Supabase client and validation

- Move Supabase/Stripe initialization inside GET/POST handlers for lazy loading
- Add validation for missing environment variables in runtime
- Improve error handling in payment intent creation
- Clean up next.config.js environment variable configuration

This fixes potential build-time failures when environment variables are not available
during static generation.
