fix: all testing gates configured correctly

- vitest.integration.config.ts: root frontend (matches vite.config.ts)
- cargo-deny: fixed config for v0.19.8 (removed invalid advisory fields)
- Playwright: e2e at project root, testDir matches
- TypeScript: compiled inside build step (tsc -p tsconfig.json)

Full gate status:
  fmt ✓  clippy ✓  ESLint 0 ✓  vitest 24/24 ✓  tsc ✓  build ✓
  cargo audit ✓  cargo deny ✓  integration config ✓
