feat(licenses): improve development setup and refactor email handling

- Updated development script in package.json to load environment variables from dotenv.
- Refactored email imports to use named exports for better clarity.
- Removed unused database expiration logic and adjusted license validation to rely on Stripe subscription status.
- Enhanced error logging in webhook processing and improved console output for server status.
- Updated SMTP configuration to use more descriptive environment variable names.
- Removed the expiresAt field from the database schema to streamline license management.
