homelab/manifests/core/dashy.yaml
Nik Afiq d44295f569 fix: add resource requests/limits and probes to workloads that had none
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.
