Extract MetricsPanel component and use it in admin capsule detail page

Moves all Chart.js metrics logic (polling, smoothing, chart init/update)
into a reusable MetricsPanel component with 'full' and 'compact' layout
modes. The admin capsule detail page now reuses MetricsPanel, TerminalTab,
and FilesTab — no duplicated code.
