Stage 7 of REFACTOR_PLAN.md (findings #16). Covers dashy, glances, ca-installer, authentik-proxy-outpost, jellyfin, qbittorrent/jdownloader main containers (their gluetun sidecars already had probes), and all 4 Immich Deployments -- previously none of these had any protection against one workload starving another on this fixed-capacity cluster, nor automatic restart on hang. Values are sized from live `kubectl top pod` baselines gathered this session (not guessed): e.g. Jellyfin/Immich-server were observed at ~3.1-3.3Gi resident, so their limits give headroom above that (4Gi) rather than an arbitrary round number. Used tcpSocket probes instead of httpGet wherever I wasn't certain of an app's exact health-check path (Immich, Postgres/Redis), to avoid a wrong path causing false probe failures on a live service. This is Kubernetes-native and takes effect on next pod restart, but should still be rolled out watching `kubectl top`/restart counts rather than pushed and forgotten -- limits set too low can OOMKill under real load.
