Pull request overview

This PR adds two integration tests for the Resource lock functionality to verify error handling scenarios: attempting to create conflicting lock types on the same resource, and attempting to create a lock with an invalid entity ID.

Key Changes

• Added TestTryToLockTwoResourcesWithTheSameType to verify that creating a second lock with a different lock type on the same resource produces an error
• Added TestTryToCreateWithInvalidData to verify that attempting to create a lock with a non-existent entity ID returns the expected error message
• Imported testify/assert and testify/require packages for improved test assertions
