feat: Add GitHub Actions workflows for Docker build, publish, documentation deployment, and quality checks

- Implemented `docker-build.yml` for building and pushing Docker images with multi-platform support, Trivy security scanning, and conditional builds based on commit messages.
- Created `docker-publish.yml` for streamlined Docker image publishing with Trivy vulnerability scanning on push events.
- Added `docs.yml` to automate documentation deployment to GitHub Pages, including a custom HTML structure and markdown conversion.
- Introduced `propagate-changes.yml` to automate PR creation for synchronizing changes between main, development, and feature branches.
- Established `quality-checks.yml` for running backend (Go) and frontend (React) quality checks, including tests and linting.
- Developed `release.yml` for generating changelogs and creating GitHub releases upon version tag pushes.
- Set up `renovate.yml` for automated dependency updates on a daily schedule.
