Feature: Edit containers

- Introduce a transactional approach for editing containers. This ensures that all changes are applied atomically, and if any step fails, it can be rolled back.
- Add functions for creating, starting, stopping, removing, and renaming containers within the transactional context.
- Convert YAML configuration for containers into a struct (`YAMLContainerParams`) and add a function to convert this struct into `ContainerCommandParams`.
- Add a new endpoint and handlers for editing a container. This includes a new GET endpoint to render an edit form and a POST endpoint to handle form submissions for editing containers.
- Modify the `FromYAMLStructToCmdParams` function to correctly handle ports by splitting them into a slice.
