[project-42.dev] Fix learner-data policy label contrast

[hcs-platform-app]

Problem

The new learner-data page renders two eyebrow labels at a 3.46:1 contrast ratio on the navy policy panels. WCAG 2.1 AA requires 4.5:1 for this text size.

Reproduction

1. Build site release 0.17.0 from branch feat/learner-data-disclosure-ab5684.
2. Run npm run test:browser.
3. The critical learner-state accessibility test fails on /learner-data.
4. Axe reports .policy-status > div > .eyebrow and .policy-machine-readable > div > .eyebrow.

Expected

All text on the learner-data page meets the WCAG AA contrast threshold and the browser accessibility gate passes.

Actual

Both labels inherit #626b7b on #0b1225, producing 3.46:1 contrast.

Acceptance criteria

• The two policy-panel eyebrow labels meet or exceed 4.5:1 contrast.
• The complete nine-test browser suite passes with no WCAG A/AA violations.
• The fix is included in the 0.17.0 release evidence.
