refactor(web): compact system status into a single card alongside metrics

Replace the separate two-card row with a single compact 'System Status'
card placed as the 5th column in the metrics grid. Shows green/red dots
for Plugin Runtime and Box Runtime. Click to expand a popover with
connection details (backend, profile, sandbox count).
