feat: floating contact bar, remove pricing contact links, fix admin hooks

- Add FloatingContact bar (Записаться + Instagram) visible while scrolling
- Hides on hero and near contact section, centered at bottom
- Move BackToTop button up to avoid overlap
- Remove redundant ContactHint from Pricing section (floating bar covers it)
- Fix React hooks order violation in AdminLayout (early return before useEffect)
