Fix: Multiple TypeScript build errors for production

- Remove unused NextAuthOptions import, use inferred types
- Add 'as const' to session strategy
- Add explicit callback parameter types with optional properties
- Update Stripe API version to 2025-11-17.clover
- Make Stripe and Resend initialization conditional for build time
- Update next-auth.d.ts type declarations
