feat: add README Insight compact card in Generator section

[RosheshChaware]

Description

Fixes #6095

This PR adds a new compact UI widget called README Insight inside the Generator section below the “README Health Breakdown” card.

The widget improves dashboard completeness by utilizing the previously empty space and provides quick actionable README improvement tips in a minimal, dark-theme compatible design.

Features added:

• Small card titled README Insight
• Displays a single dynamic tip from a static list:
  • Add badges for credibility
  • Improve description clarity
  • Add installation steps
  • Include social links
• Shows a small badge: Health Boost +X%
• Lightweight hover/fade animation (optional)
• Fully UI-only implementation (no logic/backend changes)

No existing components were modified.

Pillar

• 🎨 Pillar 1 — New Theme Design
• 📐 Pillar 2 — Geometric SVG Improvement
• 🕐 Pillar 3 — Timezone Logic Optimization
• 🛠️ Other (Bug fix, refactoring, docs)
