This PR introduces a new social media icon strip to the footer, enhancing user engagement without disrupting existing functionality. It's great to see the reuse of existing data structures for consistency. Additionally, the inclusion of accessibility features is commendable. Please ensure that the new icons are tested thoroughly, especially in relation to the resilience tests previously implemented for the SocialsSection component. Thank you for your contribution!

This is a great UI enhancement! Adding the social icon strip to the bottom bar makes the footer feel much more polished and standard. I love how you took the time to update all the corresponding test files to ensure accessibility and mouse interactivity coverage remain intact.

Everything looks solid and the checks are passing!

Label Justification:

• \level:critical: Assigned based on 4 files changed (the footer component and its 3 comprehensive test suites).
• \quality:clean: Excellent test coverage updates and semantic ARIA navigation labels for the new strip.
• \ ype:feature: Adds a new social icon strip to the UI.
• \mentor:Aamod007: Assigned as required.
