GitHub Actions workflow for Cypress tests

[gtryus]

• launchs a custom version of the dev server with the latest packages for vite testing
• sets the vite optimize deps so it is not run during tests
• tests are run in a docker instance
• write was added to packages.json to support running stamp
• npm run cy:docker:build - sets up containers ... reloads dependencies
• npm run cy:docker - runs tests each time
• npm run cy:docker:down - removes containers and network
• add docker cypress tests to github actions
• add docker clean up
• aggressive agent clean up for docker
• separate cypress tests into their own job
• Updated the job to build the Docker image and start the container directly, enhancing efficiency.
• Added a wait step to ensure the application is ready before running Cypress tests.
• Modified cleanup steps to stop and remove the Docker container after tests, ensuring a clean environment.
• Changed the working directory to /app/src/renderer for the renderer`s Vite dev server.
• Updated the comment to specify that the command runs the Vite dev server instead of the full Electron app.
• Added a step to create an index.html file with environment variables for the Vite application.
• Implemented a verification step to check for the existence of necessary environment files before building the Docker image.
• Improved logging for container status and logs during the application startup process to aid in debugging.
• Introduced a new step to run Vite optimization for Cypress tests before executing the tests, improving test performance and reliability.
• Add step to install root dependencies and stamp build with date and time
