Current topic: "Diagnosing Data Loading Failures via Logging"
Topic summary: To diagnose the `ComposeTimeoutException` in regression tests, I am adding comprehensive logging to the data layer. Specifically, I will log the vault URI being set, the paths being accessed by `VaultStorageImpl`, and the results of `listVehicleIds` and `loadAll` in `VehicleRepositoryImpl`. This will allow me to see if the storage is looking in the correct location and if it's successfully reading the seeded fixture data. I'll then examine these logs in the GMD test output to pinpoint the failure.

Strategic Intent: I will add detailed logging to `VaultStorageImpl` and `VehicleRepositoryImpl` to trace the data loading process and identify why the vehicle list is appearing empty in regression tests.
