[stephanbcbauer]

Description

This pull request upgrades the project to use Angular 21 and Node.js 22, along with updating related dependencies and configuration files. The changes ensure compatibility with the latest versions of Angular and Node.js, update the Docker and CI/CD pipeline environments, and fix some minor code issues. Below are the most important changes grouped by theme.

Major framework and dependency upgrades:

• Upgraded Angular dependencies to version 21.x in frontend/package.json and updated related packages such as rxjs, zone.js, keycloak-angular, and dev tools. TypeScript is also upgraded to 5.9.3. [1] [2]
• Updated the changelog to note the upgrade to Angular 21 and dependencies.

Node.js version updates across environments:

• Changed Node.js version from 18.x/20.x to 22.x in all CI/CD workflow files (.github/workflows/*) and documentation (INSTALL.md). This affects build, test, and deployment pipelines. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10]
• Updated the frontend Dockerfile to use node:22-alpine for builds.

Configuration and build system updates:

• Updated Helm chart versions and app versions for frontend and backend to reflect the new releases. [1] [2] [3]
• Changed Angular CLI and builder configuration in frontend/angular.json to use buildTarget instead of browserTarget, and added new schematics configuration for Angular 21. [1] [2]
• Added a new frontend/postcss.config.js for PostCSS plugins, including Tailwind CSS support.

Bugfixes and minor code improvements:

• Fixed parameter naming in the alerts mock handler to use notificationId instead of alertId, improving consistency and reducing confusion. [1] [2]
• Updated the Angular JSON file to reference the correct zone.js path.

These changes collectively modernize the codebase, improve compatibility and maintainability, and address minor bugs.

@stephanbcbauer I fixed the helm chart partly. The postgres issue has been fixed (the chart installs but fails at some point). The rest of the helm chart could be related to the unit test I think.

@stephanbcbauer I fixed the helm chart partly. The postgres issue has been fixed (the chart installs but fails at some point). The rest of the helm chart could be related to the unit test I think.

@stephanbcbauer further info. I've built it locally and run in it with minikube.

The frontend returned the following error while the backend worked fine:
