Fix admin search for Address and Contact company foreign keys

[bhumin18]

Summary

Fix a Django admin search error for the Address and Contact models.

Problem

Searching in the Address or Contact admin pages raises the following error because search_fields includes the company ForeignKey directly:

FieldError: Unsupported lookup 'icontains' for ForeignKey or join on the field not permitted.

Django attempts to apply the icontains lookup to the ForeignKey, which is not supported.

Fix

Update the admin search configuration to search using the related company's name by replacing:

• company → company__name

in both AddressAdmin and ContactAdmin.

Testing

• Reproduced the error by searching in the Django admin.
• Applied the fix.
• Verified that searching no longer raises the exception.
