Testing

About 84 tests. PostgresIntegrationTestSupport uses Testcontainers postgres:16-alpine for Flyway and persistence tests.

From splick-backend:

./gradlew :services:expense-service:test

Add a use-case test when you change a business rule. Add a migration test when you change Flyway SQL. Contract changes belong in OpenAPI and a client test, not only a controller unit test.
