Add SonarQube configuration and update .gitignore

This commit introduces a SonarQube configuration setup, adds an .idea/.gitignore file, and expands the root .gitignore file. The SonarQube setup includes a GitHub Actions workflow and a project properties file. The .gitignore files are updated to properly ignore files for JetBrains IDEs, local testfiles, SonarQube, and others.
