Nodes Screen Verbosity Reduction

Reduce unnecessary verbosity from the Nodes/Node/Runners screen - No prose on screen - No duplication of information: 5 runners, 5 runners, running, 5 active. n4-2-default-gha-1actions.runner.jaah-ai-jaah.n4-2-default-gha-1.servicegha-1 · registered. Runners -20 times. "on this host" - where else if we are looking at this host??? - Icons instead of Icon+Word - Show status of each runner similar to github - Idle, Active (no words). One shortest name of the runner. If Active show which Action it is running (briefly)  

Node page de-verbosed across all tabs (icons, no prose or duplicates); runner rows show slot, GitHub Idle/Active, and the running job. PR #4767 merged; CI gate green. Jaah Deploy failed on a runner-host runc /proc fault; operator accepted.
