test(coverage): drive N-Z pages + api/index.ts + hooks to >=95% (#132)

Pages-batch-B coverage push (filenames N-Z plus src/api/index.ts and
src/hooks). Adds render/unit tests for the previously-uncovered static
pages (NotFound/Privacy/Security/Terms/UseCases/UseCaseDetail), the
SettingsPage PAT + deploy-TTL flows, VaultPage, the TeamPage and
ResourcesPage component renders, the ResourceDetailPage branch
supplement, the useDashboardCtx singleton store, and ~66 api/index.ts
endpoint-wrapper cases via a mocked-fetch seam. Adds @vitest/coverage-v8
so per-file coverage can be measured. npm run gate green.
