fix: mobile terminal container height - use flexbox throughout

- Change .mobile-terminal-content to display: flex with flex-direction: column
- Change .terminal-wrapper.mobile to use flex: 1 instead of position: absolute
- Change .terminal-container to use flex: 1 instead of height: 100%
- Ensures proper height calculation in flex layout chain
