feat(storage-service): Update storage configuration and enhance service initialization

- Changed the default bucket name in `appsettings.Development.json` from "storage" to "goodgo" and updated MinIO endpoint and credentials for improved access.
- Modified the service initialization in `Program.cs` to include the environment name, enhancing configuration flexibility.
- Added a missing namespace in `CustomWebApplicationFactory.cs` for better test setup.
- Removed obsolete unit test files for `CreateSampleCommandHandler` and `SampleAggregate`, streamlining the test suite.
