Implement the new summary dashboard with node info and logs. Replace the previous metrics dashboard with the new dashboard which has multiple screens for node summary, metrics and editing network config. Port the old metrics dashboard to the tview library and assign it to be a screen in the new dashboard, accessible by F2 key. Add a new resource, infos.cluster.talos.dev which contains the cluster name and id of a node. Disable the network config editor screen in the new dashboard until it is fully implemented with its backend. Closes siderolabs/talos#4790. Signed-off-by: Utku Ozdemir <utku.ozdemir@siderolabs.com>
