feat(registration): new attribute type added in registration application endpoint

[AnuragNagpure]

Description

Enhance the /api/administration/registration/applications?size=10&page=0 endpoint by adding a new attribute "type" to the response, which indicates whether the application is "external" or "internal". This information is available at the application level in the database.

Why

Retrieve the "type" information from the application-level data in the database.
Ensure the "type" attribute is properly mapped and included in the endpoint response.
Update the existing response structure to include the new "type" attribute for each application in the "content" array.

Issue

#842
