Pull request overview

This PR upgrades the project to Spring Boot 4.0.x and updates related dependencies and APIs across the main library, development sample apps, and the integration test suite. It also modernizes parts of the build/test infrastructure (Testcontainers, Maven compiler/processor setup, and a new Docker test build image).

Changes:

• Upgrade Spring Boot parent to 4.0.5, update key dependencies (springdoc 3.x, spec-arg-resolver 4.x, Sentry starter, Testcontainers artifacts), and adjust imports/APIs for Spring Boot 4.
• Rework integration tests to use a shared Postgres Testcontainers base (AbstractEssenciumIntegrationTest) and reorganize integration-test “app” packages.
• Update mail handling to be gated by a new mail.enabled property, and adjust JSON filtering/advice to work with the new Jackson/Spring stack.

essencium-backend/src/main/java/de/frachtwerk/essencium/backend/configuration/properties/MailProperties.java:48

• MailProperties.enabled is introduced without a default, so it will default to false when not configured. That makes SimpleMailService.sendMail(..) a no-op by default (breaking existing setups where mail.* is configured but mail.enabled is not). Consider defaulting enabled to true for backwards compatibility (or documenting and updating all example configs to set it explicitly).

  private static final String SMTP_PROTOCOL = "smtp";

  private boolean enabled;
  private String host;
  private Integer port;
  private String username;
  private String password;

essencium-backend/pom.xml:156

• spring-boot-starter-webmvc-test is a test-only starter but is currently added without <scope>test</scope>, which will pull test infrastructure into the main artifact/runtime classpath. Set its scope to test (or remove it if spring-boot-starter-test already provides the needed pieces).

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>

essencium-backend/src/testIntegration/java/de/frachtwerk/essencium/backend/test/integration/app/model/representation/assenmbler/TestUserAssembler.java:23

• Package/directory name assenmbler looks like a typo (should be assembler) and is inconsistent with the rest of the codebase (e.g. de.frachtwerk.essencium.backend.model.representation.assembler). Consider renaming the package/folder to avoid long-term confusion and mismatched imports.
