Add initial project configuration and CI/CD workflows

- Created pyproject.toml to define project metadata and dependencies for the watcher-visio dashboard.
- Added CI workflow in ci.yml for automated testing, linting, and security checks on push and pull request events.
- Introduced docker-build.yml for building and releasing Docker images, including steps for tagging, logging in to the registry, and generating release notes.
