webui: improve process tree view in capa Explorer Web

[s-ff]

We currently display the parent-child process tree as a treeview, which works well. However, we display the capabilities found in each process using a tooltip that appears on hover. To improve this, I propose implementing a reactive table positioned vertically to the right of the tree view. This table would display the rule matches for a given process and update dynamically when a process row is clicked in the tree view.
