merge: feat(footer): enhance footer with social media icons (#8248)

## Description

Closes #6054

### Summary

Adds a compact icon-only social media strip to the footer's bottom
copyright bar while preserving the existing "Connect" section.

### Changes

* Added a social media icon strip to the footer bottom bar.
* Reused the existing `socialLinks` data and `SOCIAL_ICON_MAP`.
* Excluded the creator GitHub link from the bottom strip to avoid
duplicate GitHub icons.
* Added an accessible navigation landmark with `aria-label="Social media
links"`.
* Ensured all external links use `target="_blank"` and `rel="noopener
noreferrer"`.
* Updated Footer-related tests to account for the new icon strip and
maintain test coverage.

## Pillar

* [ ] 🎨 Pillar 1 — New Theme Design
* [ ] 📐 Pillar 2 — Geometric SVG Improvement
* [ ] 🕐 Pillar 3 — Timezone Logic Optimization
* [x] 🛠️ Other (Bug fix, refactoring, docs)

## Visual Preview

N/A (UI enhancement to the existing footer)
