fix: mobile terminal black screen - replace grid with flexbox layout

- Root cause: CSS Grid 1fr row got 0 height inside flex parent
- Fix: Replace grid layout with flexbox column for mobile terminal wrapper
- Header and keys strip use flex-shrink: 0
- Content area uses flex: 1 to fill remaining space
- Remove debug logging
