Trigger Maven workflow on main and dev pushes

Update CI workflow to run on pushes to both `main` and `dev` branches (was only `dev`). This ensures the Maven build runs for direct pushes to main as well; pull_request triggers already cover `main`, `dev`, and `release`. Changed .github/workflows/maven-build.yml accordingly.
