Console plugin: BuildJob list and detail pages

[vtz]

Context

Add the core pages to the console plugin so users can browse and inspect BuildJobs from the OpenShift web console.

Depends on: #44 (scaffold)

Scope

BuildJob List Page

• Navigation item "Builds" in the Developer perspective sidebar
• Table view: Name, Phase (with colored status badge), Board, Platform, Architecture, Source, Age
• Namespace selector integration
• Filter by phase (Pending / Running / Succeeded / Failed)
• "Create BuildJob" action button

BuildJob Detail Page

• Header with name, phase badge, board/platform/arch summary
• Overview tab: source info (git URL + revision or PVC), toolchain image, timeout, stages list with status
• Pipeline tab: link to / embed the associated PipelineRun (using status.currentPipelineRun)
• YAML tab: standard YAML editor (provided by SDK)
• Events tab: Kubernetes events for the resource

SDK Hooks

const [buildJobs, loaded, error] = useK8sWatchResource<BuildJob[]>({
  groupVersionKind: {
    group: 'bob.redhat.com',
    version: 'v1alpha1',
    kind: 'BuildJob',
  },
  isList: true,
  namespace: activeNamespace,
});

Design

Use PatternFly components to match the native OpenShift look and feel:

• TableComposable for list view
• DescriptionList for detail overview
• Label / LabelGroup for phase badges
• Tabs for detail sub-navigation
