merge: fix: add missing footer i18n keys for support, guidelines, and faq (#7287)

## Description

Fixes #7284

Added the missing translation keys (`support`, `guidelines`, `faq`) to
the `footer` object across all i18n locale JSON files (`en.json`,
`de.json`, `es.json`, `fr.json`, `hi.json`, `ja.json`, `ko.json`,
`pt.json`, `zh.json`). This resolves the issue where raw key names were
leaking in the production footer.

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