@dapr/maintainers-java-sdk would be nice to get feedback. I still need to decide what to do with the current 1.18

We deprecate SB 3.5 and we do updates on deps best effort and suggest people to move to SB 4. Shall we backport this to 1.18.x ?

Pull request overview

Migrates the repository’s Spring Boot integration surface to Spring Boot 4.x by consolidating previously SB4-suffixed packages/modules into the default Spring Boot path, updating example/test dependencies (including web + test client stacks), and adjusting CI to run the unified Spring Boot 4 integration suite.

Changes:

  • Consolidate Spring Boot 4 test/example code by removing SB4-specific module trees and renaming SB4-suffixed Java packages/artifacts to the default Spring Boot package names.
  • Update Spring Boot examples and SDK integration tests to use Spring Boot 4 dependency coordinates and newer testing/client APIs.
  • Update build pipeline to run integration tests against Spring Boot 4.0.5 and upload the correct reports.

we rely on [Testcontainers](https://testcontainers.com) to create the entire setup which enable us to run the workflow end to end.

But the magic behind the test can be located in the [`DaprTestContainersConfig.class`](orchestrator/src/test/java/io/dapr/springboot4/examples/orchestrator/DaprTestContainersConfig.java) which defines the configuration for
all the Dapr containers and the `worker-one` and `worker-two` applications. Check this class to gain a deeper understand how to configure
