feat: add "Night Owl vs. Early Bird" coding personality calculator widget to Tracker dashboard

[Sushma-1206]

💡 Feature Proposal

Currently, the Tracker page shows a clean list view of a developer's issues and pull requests. To make this data more engaging and insightful, we should add a visual coding personality tracker that calculates whether a user is an Early Bird ☀️ or a Night Owl 🦉 based on the timestamps of their contributions.

🛠️ How it will work:

1. Time Extraction: Look at the Created timestamp column fields for all fetched pull requests and issues.
2. Bucket Categorization:
   • Early Bird: Contributions created between 5:00 AM and 11:59 AM.
   • Night Owl: Contributions created between 10:00 PM and 4:59 AM.
3. UI Display: Add a minimalist, responsive analytics card row right above the dynamic table view. It will feature:
   • A prominent personality badge text banner matching the winning bucket.
   • A clean horizontal progress bar demonstrating the balance percentage distribution between morning and late-night coding sessions.

🎨 Visual Layout Location

• Positioned horizontally below the search filters block and directly above the ISSUES (4) / PULL REQUESTS (6) tab selector row.

🚀 Checklist:

• Create timestamp parsing utility function block.
• Design the UI metric card wrapper using Tailwind CSS variables.
• Integrate local timezone handlers to ensure calculated hours match local user activity accurately.
