bug: E2E failures after PR #997 — database filter/sort tests and accessibility contrast violation

[sw-factory-automations]

Description

After merging PR #997 (feat: extend axe-core accessibility audit to database view pages), 4 E2E tests fail when run against the live site (https://memo.software-factory.dev):

• 3 failures in e2e/database-views.spec.ts — database filter/sort interactions
• 1 failure in e2e/accessibility.spec.ts — color contrast violation on workspace settings page

PR #997 modified table-view.tsx (added role="columnheader" wrappers) and calendar-view.tsx (restructured ARIA grid). The database-views filter/sort failures may be related to the table-view ARIA changes or may be pre-existing flakiness on the live site.

Failures

1. database-views.spec.ts — "add a filter and verify rows are filtered"

• prop2Cell(page, 1) expected text "World" but got empty string
• Cell at [role="gridcell"][data-col] nth(3) resolved but had no text content
• Suggests cell values are not rendering or persisting correctly in the table view

2. database-views.spec.ts — "remove a filter pill and verify all rows reappear"

• After removing filter pill, [role="gridcell"] with text "Bar" not found
• Same root cause as chore: initial project scaffold #1 — cell content not appearing

3. database-views.spec.ts — "switch between views and verify each retains its own sort/filter state"

• Timeout during fillCell — locator.fill: Target page, context or browser has been closed
• Cascading failure from cell interaction issues

4. accessibility.spec.ts — "workspace settings has no critical or serious axe violations"

• color-contrast violation (serious): text-destructive color #cc272e on dark backgrounds
• "Danger zone" heading: contrast 3.73:1 (needs 4.5:1) against #06070a
• Delete account button: contrast 3.29:1 against #2e0d11
• This is likely pre-existing and unrelated to PR feat: extend axe-core accessibility audit to database view pages (#993) #997 (which didn't touch account settings)

Acceptance Criteria

• All 3 database-views.spec.ts filter/sort tests pass against the live site
• accessibility.spec.ts workspace settings test passes (fix text-destructive contrast ratio)
• pnpm lint && pnpm typecheck && pnpm test pass

Technical Notes

• PR that introduced the regression: feat: extend axe-core accessibility audit to database view pages (#993) #997
• Affected components: src/components/database/table-view.tsx, account settings page
• The database-views failures involve [role="gridcell"] selectors — PR feat: extend axe-core accessibility audit to database view pages (#993) #997 added role="columnheader" wrappers in the table header row, which may affect cell indexing in tests
• The accessibility contrast issue affects text-destructive class used in the account settings "Danger zone" section
• 48 other E2E tests passed, ad-hoc smoke tests passed (landing, sign-in, health, auth flow)
