🔧 Fix email verification 'Not Found' error

✅ Root Cause Fixed:
- SITE_URL was pointing to quantumtaskai.com instead of actual Railway domain
- Email verification links were going to wrong domain causing 404 errors

🔧 Changes Made:
- Update SITE_URL to use quantum-ai.up.railway.app for Railway environment
- Email verification links now point to correct domain

🛠️ Added Management Command:
- Create verify_email command for manual email verification
- Usage: python manage.py verify_email user@example.com
- Useful for admin-created users or troubleshooting

✅ Expected Result:
- Email verification links now work correctly
- Users can successfully verify their emails
- Manual verification available for admin use
