Assess only reader-visible dashboard views so the assessment completes within its budget

[Copilot]

The daily dashboard view assessment reported cost as failed and was blocked by browser.newPage: Target page, context or browser has been closed after assessing only 2.5 of 69 views.

Root cause

cost declares a full-view lazy-list table alongside charts. The presenter's view-mode selection (data-mobile-view-mode, default chart) hides that table with display: none, so its lazy-view skeleton keeps aria-busy="true" indefinitely and is never scrollable into view. The assessment waited on that hidden skeleton — ~30 s scrollIntoViewIfNeeded, ~30 s hydration loop, ~5 s toHaveCount(0) — about 65 s per such page. That exhausted the flat 180 s test timeout mid-cost; Playwright then closed the browser, yielding both the cost error (locator.count: Target page ... closed) and the run-level blocker.

Changes

• tests/e2e/dashboard-view-assessment.mjs: new visibleViewSelector / visibleBusyViewSelector, plus dashboardAssessmentTimeout(pageCount) (120 s startup + 20 s per view, capped at 15 min).
• tests/e2e/dashboard-views-live.spec.mjs: scroll and await only visible views; apply the scaled timeout. Rendered-view accounting still uses the unfiltered locator, so mode-hidden views are not reported missing.
• .github/workflows/dashboard-views.yml: assess job timeout 20 → 30 min, so a capped run always finishes and uploads its summary.
• tests/unit/dashboard-view-assessment.test.mjs: coverage for the new helpers.

const visibleViews = activePage.locator(visibleViewSelector);      // [data-view-id]:visible
const busyViews = activePage.locator(visibleBusyViewSelector);     // [aria-busy="true"]:visible

A full local assessment of all 69 views now completes in ~2.6 min (previously 2.5 views in 3 min before blocking), with cost rendering all three of its views.
