add 400+ unit tests for domain and application layers

Extract ReviewLogger trait to decouple import/integrations
from diary::log_review (cross-module coupling smell).

Add in-memory fakes for all repository ports, enabling
isolated testing of every use case module without a database.

Coverage: domain+application 22% → 80%, 427 tests.

-The `application` crate has unit tests for core use cases backed by in-memory fakes from `domain`'s `test-helpers` feature. These run without a database and are the fastest feedback loop for business logic changes.
