Add CI and Docker workflows for automated testing and deployment

- Introduced a CI workflow in `ci.yml` to automate linting, testing, and security checks using Ruff and Bandit.
- Added a Docker build and release workflow in `docker-build.yml` to automate image building and pushing to the Gitea Container Registry upon version tag pushes.
- Configured steps for checking out code, setting up Python, installing dependencies, and generating release notes.
- Enhanced project automation and deployment processes, improving overall development efficiency.
