[dependabot:release-train-updater] Review bundle: bump `@playwright/test` to 1.62.1 in dashboard/site

A dependency release-train review (worker mode: `review`) analyzed `githubnext/gh-aw-cao` and prepared a review bundle instead of a live pull request, per the current safe-output routing for this run.

### Summary
- Package/ecosystem: npm — `@playwright/test`
- Manifest(s): `dashboard/site/package.json`, `dashboard/site/package-lock.json`
- Old version: `^1.55.0` → New version: `^1.62.1` (minor, devDependency only)
- Why: this was the only outdated direct dependency found across the repo's npm manifests. Root `package.json` deps were already at latest; no Go/Python/Rust manifests present; no open dependency PRs found needing repair.
- Risk: dev-only test tooling, not reachable from application source, no auth/crypto/telemetry surface.
- Validation: registry preflight (`npm view`) and lockfile-only install succeeded, isolating the lockfile diff to the `@playwright/test` entry. Full `npm install`/`npm test`/`npm run test:e2e`/`npm run typecheck` could not be executed in this review sandbox — recommend confirming those pass in CI before merge.

The full analysis, patch diff, and validation notes are attached in the published review-bundle artifact for this workflow run (bundle: `playwright-test-1.62.1`).

**Action:** A maintainer with write access to `githubnext/gh-aw-cao` should review the attached bundle and, if it looks good, apply the one-line `package.json`/`package-lock.json` change (bump `@playwright/test` `^1.55.0` → `^1.62.1` in `dashboard/site/`) via a normal PR, running `npm test && npm run test:e2e && npm run lint && npm run typecheck` from `dashboard/site/` as the acceptance check.

Agent prompt

Bump the `@playwright/test` devDependency in `dashboard/site/package.json` from `^1.55.0` to `^1.62.1`, run `npm install` in `dashboard/site/` to update `package-lock.json`, then run `npm test`, `npm run test:e2e`, `npm run lint`, and `npm run typecheck` from `dashboard/site/` and confirm they all pass. Open a PR with the resulting changes.

Start with dashboard/site/package.json and dashboard/site/package-lock.json, then run npm install from dashboard/site/ to update the dependency entries. Run npm test, npm run test:e2e, npm run lint, and npm run typecheck; the work is done when @playwright/test is 1.62.1 and all checks pass.
