Add Integration Tests for User Sharing API

[BimsaraBodaragama]

Description

Add integration tests for the User Sharing API to validate successful user sharing/unsharing, ensuring correct request handling and response accuracy. Since user sharing is asynchronous, these tests should confirm successful sharing/unsahring by verifying the shared organizations through a GET request, ensuring expected API behavior under various valid inputs.

Tasks

• Add success case tests.
• Add failure case tests.
• Verify response structure and error handling.

Version

7.1.0
