Subject: [PATCH] Add Lemon Squeezy environment variable schema validation and
 removed NODE_ENV from production variables, as it causes issues in Vercel

- Implement `getLemonSqueezyEnv` function to validate required environment variables for Lemon Squeezy integration using `zod`.
- Ensure `LEMON_SQUEEZY_SECRET_KEY`, `LEMON_SQUEEZY_SIGNING_SECRET`, and `LEMON_SQUEEZY_STORE_ID` are present and valid.
