refactor: UI cleanup - move respawn controls, remove mode label, fix dir width

- Move respawn controls from toolbar to session options modal
- Remove unnecessary Mode label from session options (visible in tab)
- Increase directory input width from 200px to 350px
- Add RTL direction to directory display to show end of long paths
- Add respawn status indicator with stop/configure buttons in modal
