[AZ-456] Test infrastructure: Vitest + MSW + Playwright + scripts

Scaffolds the Blackbox test project per AZ-456 / environment.md across
the three profiles:

- fast  : Vitest 3.x + jsdom + MSW 2.x + RTL/jest-dom; tests/setup.ts
          boots the MSW Node server with onUnhandledRequest:'error',
          afterEach resets handlers, clears bearer + navigate-to-login
          spy. Default handlers ship for every suite service plus OWM
          and tile stand-ins. Fixtures mirror seed_* in test-data.md.
- e2e   : Playwright ^1.49 with chromium + firefox projects against the
          suite docker-compose stack; owm-stub + tile-stub Bun servers,
          playwright-runner image, seeds.sql for the test-db.
- static: scripts/run-tests.sh extended — tsc --noEmit (test config),
          vite build, ripgrep checks (with grep -r fallback), CSV
          report at test-output/static-report.csv per AC-7 columns.

Smoke tests cover AC-3, AC-4 (fast, 5 tests, PASS) and AC-1, AC-2,
AC-5, AC-8 (e2e, gated by Risk 4 docker availability). Static profile
(13 checks) PASS — STC-SEC1 (no literal OWM key) lifted from
QUARANTINE per AZ-447 with a narrowed pattern.

Files:
  +24 tests/**, +10 e2e/**, +vitest.config.ts, +tsconfig.test.json
  ~package.json (test scripts + devDeps for vitest, @testing-library/*,
   msw, @playwright/test, jsdom, @types/node, @vitest/coverage-v8)
  ~scripts/run-tests.sh, scripts/run-performance-tests.sh — switched
   RESULTS_DIR to test-output/, compose path to project-local
  ~.gitignore — added /test-output/

Verification:
  bun run test:fast        → 11 / 11 PASS
  ./scripts/run-tests.sh   → static 13/13 + fast 11/11 PASS, exit 0

Tracker: AZ-456 → In Testing.
