test: add component tests for all 8 UI components

Add 92 new tests across 8 test files covering DriverStatusCard, SnapshotsPage, PVCDetailSection, StorageClassesPage, VolumesPage, MetricsPage, OverviewPage, and BenchmarkPage. Includes shared test-helpers.tsx with fixtures and a lightweight CommonComponents mock. Total tests: 67 → 159. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
