refactor: streamline job status retrieval and clean up repository interface

- Simplified the job status retrieval process by consolidating logic into a single `getJobStatus` function.
- Removed redundant checks and methods from the `CustomJobRepositoryInterface` and `CustomJobRepository`.
- Updated the `getHorizonJobStatus` method in `ApplicationDeploymentQueue` to directly utilize the new `getJobStatus` function.
- Enhanced the `isThereAJobInProgress` method to improve clarity and maintainability.
