[#00] refactor backend test DI style and align Quartz job wiring

[igorsatsyuk]

What changed

• Replaced @Autowired private-field injection with constructor injection in backend test classes across command-service, event-store-service, audit-writer-service, and query-service.
• Added @TestConstructor(autowireMode = TestConstructor.AutowireMode.ALL) where tests now rely on constructor-based test dependency injection.
• Refactored ReconciliationQuartzJob to a Quartz-safe setter-only injection path (no-args constructor + @Autowired setDependencies(...)).
• Updated ReconciliationQuartzJobTest to instantiate the job with no-args constructor and wire collaborators through setDependencies(...).
• Aligned IntegrityCheckIntegrationTest with constructor-based test injection style.

• backend/query-service/src/test/java/lt/satsyuk/distributed/audit/query/jobs/ReconciliationQuartzJobTest.java

Why

• Enforces a consistent DI style and removes field injection anti-patterns in tests.
• Keeps Quartz runtime instantiation behavior stable while preserving explicit dependency wiring in ReconciliationQuartzJob.
• Fixes test-compile mismatch caused by constructor signature changes in the Quartz job.

Verification

• mvn test passes locally.
• mvn verify passes locally.

Pull request overview

This PR updates query-service tests to match recent DI/wiring changes, resolving test compilation issues caused by mismatched construction patterns for Spring-managed components.

Changes:

• Updated IntegrityCheckIntegrationTest to use constructor-based injection via @TestConstructor.
• Updated ReconciliationQuartzJobTest to construct the Quartz job via no-args constructor and inject dependencies through setDependencies(...).
