Fix terminal layout and improve mobile UX

- Restructure session-view to use proper flexbox layout (header/xterm/buttons)
- Container now exactly fits viewport height (100vh)
- Header shows command and working directory stacked
- XTerm gets all remaining space with horizontal scrolling
- Mobile buttons integrated into layout instead of overlaying
- Replace setTimeout with requestAnimationFrame for better performance
- Add isPreview parameter to renderer for future preview scaling
- Disable pointer events on preview terminals so clicks pass through
