frontend: workload: Fix Pods overview chart to reflect failing pods

[xonas1101]

What this fixes

Fixes #6090.

On the Workloads overview, the Pods status chart always reported 100% / "N Running", even when pods were in Error, CrashLoopBackOff, ImagePullBackOff, Pending, etc. — it was structurally incapable of ever showing an unhealthy pod.

Root cause

WorkloadCircleChart computes the failed count with a replica-mismatch check:

workloadData?.filter(item => getReadyReplicas(item) !== getTotalReplicas(item)).length

getReadyReplicas/getTotalReplicas only read replica fields (status.readyReplicas, status.numberReady, spec.replicas, status.currentNumberScheduled, status.desiredNumberScheduled). A Pod has none of these, so both helpers return 0, the check is always 0 !== 0 → false, and the Pods tile can only ever render 100%. This is correct for replica-based kinds (Deployment/StatefulSet/DaemonSet/ReplicaSet) but wrong for Pods.

Approach

• Add an optional categorize() classifier to WorkloadCircleChart. When provided (Pods only), the chart renders a multi-segment health ring instead of the binary one:
  • 🟢 healthy — Running & Ready, or Succeeded
  • 🟡 degraded — Running but not Ready
  • ⚪ transitional — Pending / Terminating (not failures)
  • 🔴 failed — Failed phase, or a container in CrashLoopBackOff / ImagePullBackOff / etc.
• Replica-based tiles keep their existing binary behavior unchanged.
• getPodHealth() derives the category from the same signals the Pods list already shows (phase, readiness, container waiting reason, deletionTimestamp), so the chart and the list can't disagree. Notably, Terminating and Pending pods are transitional, not failures, which avoids a false-alarm red arc.

Before / after

On a cluster with 89 pods (50 Running&Ready, 13 not-ready, 19 Pending/Terminating, 7 genuinely failing):

	Center	Legend
Before	100%	89 Running
After	56.2%	50 Running · 7 Failed · 13 Degraded · 19 Other

Testing

• Updated the Overview storyshot (Pods tile now reflects real health instead of a flat 100%).
• Charts storyshots for the replica-based tiles are unchanged (binary path untouched).
• tsc and eslint clean; i18n strings extracted.

Pull request overview

This PR fixes the Workloads overview “Pods” status chart so it can reflect unhealthy pods by introducing pod-specific health categorization, while keeping replica-based workload tiles on the existing binary replica-mismatch behavior.

Changes:

• Added an optional categorize() path to WorkloadCircleChart to render a multi-segment health ring (healthy/degraded/transitional/failed).
• Implemented getPodHealth() to bucket pods based on phase/readiness/container state and wired it into the Pods tile.
• Added the new i18n key Other and updated the Overview storyshot snapshot accordingly.
