🧪 [add unit tests for SubmissionUploadExecutor]

- Implement Hilt integration test for SubmissionUploadExecutor.
- Resolve duplicate bindings by uninstalling DispatcherModule.
- Use @bindvalue for DispatcherProvider to simplify Hilt test wiring.
- Verify Hilt wiring and IO dispatcher usage deterministically.
