Fix dashboard assessment summary timeout

[Copilot]

Dashboard view assessments could exceed Playwright’s fixed 180-second timeout before writing summary.json, leaving the reporting job without an artifact.

• Assessment timeout

  • Configure Playwright with the existing bounded maximum assessment timeout, allowing setup plus per-view evaluation to complete and emit a summary.

  timeout: maximumDashboardAssessmentTimeoutMs,

• Regression coverage

  • Verify the effective Playwright configuration remains tied to the assessment timeout bound.

• Fixes Dashboard view assessment #13496
