Redesign Scripture Index with BSB verse text and row layout; v1.2.1

- Replace cramped auto-fill grid with full-width row layout (reference | verse text | arrow)
- Fetch BSB passage text from bible.helloao.org, grouped by chapter to minimize API calls
- Display 2-line italic excerpt of each passage beneath the lesson title
- Hover state reveals arrow and highlights row in gold
- Mobile-responsive collapse to single column
