Implement headlamp-tns-csi-plugin

Full plugin implementation with 6 pages, K8s resource filtering,
Prometheus metrics parsing, kbench benchmark runner, and 67 unit tests.

## Pages
- Overview: driver health, storage summary, protocol distribution chart, non-Bound PVC alerts
- Storage Classes: tns-csi SC table with slide-in detail panel + protocol notes
- Volumes: PV table with full CSI attribute detail panel
- Snapshots: VolumeSnapshot CRDs with graceful degradation if not installed
- Metrics: Prometheus text format parser + WebSocket/Volume/CSI operation cards
- Benchmark: kbench Job+PVC lifecycle, FIO log parser, past benchmarks list

## API modules
- k8s.ts: typed resource shapes, filtering helpers, formatting utilities
- metrics.ts: Prometheus text format parser, tns-csi metric extraction
- kbench.ts: Job/PVC manifests, lifecycle management, FIO summary parser
- TnsCsiDataContext.tsx: shared React context with memoized filtered resources

## Quality
- TypeScript strict mode, zero any, discriminated union for benchmark state
- 67 tests passing (vitest + @testing-library/react)
- registerDetailsViewSection injects TNS-CSI details on PVC pages
- Graceful degradation for missing CSIDriver and VolumeSnapshot CRDs
