Refactor extension tabs layout and styles

Remove the overflow wrapper around extension tabs and move max-w/full styling to the Tabs component. Simplify classNames (tabList, cursor) and clean up shrinking/truncation classes on tab items and plugin name to improve responsiveness and layout, while preserving the openInNewWindow click behavior.
