perf: stats poll via lichtgewicht /api/stats i.p.v. /containers-dashboard

Browse Source 
De frontend haalde CPU/mem stats op via het zware /containers-dashboard
endpoint (Podman call + os.walk + systemctl subprocesses per container).
Nu gaat de stats poll via een nieuw /api/stats endpoint dat alleen de
bestaande in-memory cache teruggeeft (<5ms vs ~400ms).

- app_containers.py: /api/stats endpoint toegevoegd (cache direct return)
- app_containers.py: _STATS_SHOWN_NAMES bijgehouden per dashboard call
  (filtert infra/management containers eruit op basis van _dashboard_source)
- containers.js: pollContainersDashboardStatsOnce() gebruikt /api/stats
