FEAT: Add project logo

[Caussz]

Add and Create Logo for Project

Description:

This issue involves designing and implementing a new logo for the project. The logo should consist of the letters "FN", each in a different color, referencing the full project name already displayed in the developed header. The logo should then be converted to an .ico file and added as favicon.ico for the project.

Checklist:

• Design a logo with the letters "FN", each in a different color.
• Convert the logo to .ico format and add it as favicon.ico in the project.
• Add the logo to the PWA manifest.
• Ensure the logo is correctly displayed on iPhone and Android devices.
• Follow the tutorial provided by Professor Eduardo for detailed steps on configuring the PWA:

Notes:

• Ensure that the logo is designed to be clear and recognizable even at small sizes.
• Validate the implementation with the team leader before finalizing.
• Please check off each item on the checklist as you complete the tasks.
