Fix board dashboard layout - now uses correct board layout

- Changed board dashboard from 'dashboard' layout to 'board' layout
- This fixes the missing hamburger menu and sidebar toggle functionality
- Removed debug console.log statements from board layout
- Board dashboard now has same sidebar behavior as admin and member dashboards

The issue was that board/dashboard/index.vue was using the old 'dashboard'
layout instead of the proper 'board' layout that has rail mode support.
