feat(ui): Replace sponsor text names with logos and add hover effect

[harshchill]

Description
The section at the bottom of the landing page that lists supporting companies currently uses plain text. While functional, this is not very visually engaging and underutilizes the space for acknowledging supporters.

Problem Statement
Plain text names are not as recognizable or professional as official logos.

The section lacks visual polish and feels static.

Proposed Solution
To improve the design and give proper recognition to supporters:

Replace text names with logos: Source and implement the official logos for each company listed.

Add a subtle hover effect: Apply a simple, professional hover effect to each logo.
