fix: improve UI responsiveness for narrow sidebar widths

- Add CSS rules to prevent VSCode checkbox squeezing across all settings pages
- Fix trash icon being cut off in profile selection by adjusting button spacing
- Add min-width constraints to icon buttons to maintain visibility
- Implement responsive CSS utilities for containers under 400px width
- Add specific selectors for VSCode checkbox components to ensure proper sizing
- Reduce gap between profile action buttons and add margin separation
