feat: add collapsible reference tables for sections with >5 rows

- Tables with more than 5 rows now show first 5 with 'Show N more...' toggle
- Uses native <details>/<summary> for expand/collapse
- Keeps reference pages cleaner by reducing visual noise from long sections
- Box Model, Typography, Transitions now collapsed by default
