Address input: Search property field always filled with "admin" - cannot be removed

[yuliaGradova]

For Address input component the Search property field is pre-filled with the value "admin" and cannot be cleared or changed. This prevents users from configuring and causes the property panel to disappear entirely, making configuration impossible.

To Reproduce

1. Add Address input component to the form
2. Click on Data tab
3. Look at the Search property input field
4. Observe it is already filled with "admin" (see the video)

Expected behavior
The Search property field should be empty by default
