Implement DELETE operation for record removal in REST API

[Bradltr95]

Summary

This pull request adds the DELETE functionality to the existing RESTful API, enabling the removal of records by their unique identifiers.

Key Updates:

• Controller Layer: Introduced a @DeleteMapping endpoint to handle HTTP DELETE requests for record deletion.
• Service Layer: Implemented logic to interact with the repository and perform the deletion operation.
• Repository Layer: Utilized Spring Data JPA's deleteById method to remove records from the database.
• Error Handling: Added appropriate responses for scenarios where the record to be deleted does not exist, returning HTTP 404 status codes.

Despite ensuring the container is running and the application is built before the tests are run it is failing to connect and run the final test. Will look into these issues and resolve them tomorrow.
