Add Dark Mode Contrast Ratio Compliance to ScheduledJobs Page

[hardikkaurani]

🟢 Good First Issue

Problem

Some cron history cards on the ScheduledJobs page have low-contrast text borders, failing WCAG AAA contrast ratio accessibility standards.

Why It Matters

Accessibility compliance ensures all users including those with visual impairments can use the dashboard effectively.

Suggested Files

• frontend/src/pages/ScheduledJobs.tsx

Definition of Done

• Updated Tailwind border/opacity classes to meet AAA contrast ratio.
• Visual verification in both light and dark modes.
• npm run lint and npm run typecheck pass cleanly.

👋 Maintainer Solution Guide:

1. Open frontend/src/pages/ScheduledJobs.tsx
2. Find the cron history card component and update low-contrast border-opacity / text-gray classes to high-contrast alternatives
3. Test visually in both light and dark modes
4. Run npm run lint && npm run typecheck to ensure clean build

Perfect for frontend-focused contributors! 🎨
