feat: make first commit linkable and add birthday celebration

[Mishra-coder]

Description

This PR addresses issue #1436 by making the "First Commit" date in the project overview linkable and adding a celebratory animation for the project's birthday.

Changes

• Linkable First Commit: The "First Commit" date now links to the project's repository URL (if available).
• Birthday Celebration: Added logic to check if today matches the month and day of the first commit. If it does, a bouncing balloon is displayed next to the date.

Verification

• Verified that the date is clickable and opens the repository URL.
• Verified that the balloon icon appears on the correct date (tested by mocking the date).

Fixes #1436

Hey @Mishra-coder, as seen in the README.md file, outside contributors are not intended yet as this repository mainly has frontend code.
For instance for the feature you are trying to complete, we would need to return the commit hash in the API to be able to link directly to the repo's first commit. This logic is done in another repo.

Also, for UI changes we usually run by our product designer to make sure it's aligned with the rest of the application.
I will close the PR as it doesn't fully fulfil the feature request in the ticket and you cannot achieve it on this repo alone.

You can although still contribute to the repo in other ways, either documentation, frontend contributions, issues or discussions.
Thanks anyway for your interest in contributing to Insights!
