fix: remove placeholder office address from contact page

Removed the fake office address ('Our Office: 123 Bible Street, Faith City, FC 12345') from the contact page.

Now only showing:
- Email contact (contact@biblical-guide.com)

Changes:
- Removed address object from contactInfo array
- Removed unused LocationOn icon import
- Contact page now shows only valid contact information
