Reposition album share button to title row on desktop

- Move share button to same row as album title on desktop (>768px)
- Keep share button in status row on mobile (≤768px) for better UX
- Add album-title-row container with flexbox layout
- Implement responsive show/hide behavior for desktop vs mobile share buttons
