feat: move "Report Bug / Feature Request" button to header for improved accessibility

- Relocated the button from the bottom sidebar to the header next to the AutoMaker logo.
- Updated the button to be a compact icon-only version with a tooltip on hover.
- Adjusted the header layout to accommodate the new button placement.
- Removed the old button from the sidebar to streamline the UI.
