[AS4] - Re-design of Configuration tab of experiment summary

In Autosubmit 4.0, config files can consist on several files, so from a high-level point of view can be a tree with different leafs, so the current view for the experiment configuration is no longer suitable and doesn't work with AS4 experiments. so we need to:

• Redesign this tab
• make sure it works with previous experiments
