Update Python to 3.13 and bump various dependencies

[DerOetzi]

This pull request introduces several important updates to modernize the development environment, dependencies, and workflows for both the backend and frontend. The main focus is on upgrading the Python and Node.js versions, updating related dependencies, and aligning the CI/CD pipeline and Docker setup accordingly. Additionally, there are improvements to Angular and Tailwind CSS integration in the frontend.

Development Environment and Dependency Upgrades

• Upgraded the base Python version from 3.11/3.10 to 3.13 across .devcontainer, Docker, and CI/CD workflows, and updated the Node.js version to 24. This includes updating the devcontainer images and features, as well as the Python and Node.js setup in the GitHub Actions workflows. [1] [2] [3] [4] [5] [6]
• Updated core Python dependencies to their latest versions in core/requirements.txt, including fastapi, loguru, numpy, pandas, PyJWT, scikit-learn, and uvicorn.

CI/CD Workflow Improvements

• Bumped versions of several GitHub Actions in .github/workflows/build_project.yml for enhanced security and compatibility (actions/checkout, actions/github-script, actions/download-artifact, actions/setup-python, docker/metadata-action, docker/build-push-action). Also updated the Python version matrix and release conditions to use Python 3.13. [1] [2] [3] [4] [5] [6]

Frontend Dependency and Build Updates

• Updated Angular and related frontend dependencies to their latest versions in ui/package.json, including @ngx-translate/http-loader, zone.js, autoprefixer, jasmine-core, and karma-jasmine-html-reporter. [1] [2]

Frontend Code and Integration Enhancements

• Refactored the translation loader setup in ui/src/app/app.module.ts to use the new TRANSLATE_HTTP_LOADER_CONFIG and TranslateHttpLoader class, simplifying configuration and aligning with the updated package API. [1] [2] [3] [4]
• Migrated Tailwind CSS integration in ui/src/styles.scss from @import to the recommended @use syntax, improving style encapsulation and compatibility with newer versions.

Pull request overview

This PR modernizes the project toolchain and dependencies by upgrading the backend runtime to Python 3.13, updating CI/CD and Docker accordingly, and bumping several frontend dependencies while adjusting Angular i18n loader configuration and Tailwind integration.

Changes:

• Upgrade Python runtime targeting (Docker + packaging metadata) to Python 3.13 and update core Python dependency pins.
• Update GitHub Actions workflow versions/config and build matrix (Python 3.13; Node 24 already used for UI build).
• Bump UI dependencies and refactor ngx-translate HTTP loader configuration; adjust global styles Tailwind includes.
