Redesign Sketch top bar with tab-based interface

- Replace emoji-only buttons with tabs showing both icons and text
- Reorganize container status to hide detailed info behind (i) button
- Keep only essential info visible: hostname, working dir, git repo, and cost
- Improve layout of top banner components
