Improve extension tab UI and add /plugin proxy

Update dashboard extension UI to prevent title overflow: add truncate and max-width to the tab title, include the plugin name in the title tooltip, and hide the plugin-name label on small screens (visible from md+). Also add a '/plugin' proxy entry to the Vite dev server config so plugin requests are forwarded to the backend debug URL.
