feat: Upgrade to Node.js 24 and modernize welcome email

  - Update Node.js from v20 to v24 (.nvmrc and volta config)
  - Migrate nodemailer to v7 with AWS SESv2 API
  - Update dependencies for React 19 compatibility (@t3-oss/env-nextjs,
    next-themes, react-highlight-words)
  - Configure GitHub Actions to use .nvmrc for Node version
  - Separate newsletter subscription and welcome email error handling
  - Redesign welcome email template with modern styling (no images for
    better deliverability)
