Changed contact form email delivery to use local Maddy SMTP server for better reliability.
**Changes:**
- Created new SMTP service (lib/smtp.ts) using nodemailer
- Configured to use localhost:25 (Maddy SMTP)
- Updated contact API to use smtpService instead of mailgunService
- Installed nodemailer and @types/nodemailer
**Benefits:**
- Simpler configuration (no external API dependencies)
- Local email delivery (more reliable for internal emails)
- No API rate limits or authentication issues
- Direct delivery to contact@biblical-guide.com
**Roundcube still uses Mailgun SMTP** for outgoing emails from webmail interface.
