🧪test: update unit tests to support Redis cache dependency

- Updated unit tests to inject mocked IDistributedCache after the introduction
of distributed caching.
- All service tests now use Moq to simulate cache behavior, defaulting to cache miss scenarios to validate repository execution and core business logic
without requiring a real Redis instance.
