  Summary of changes made:

1. Backend (mcpgateway/version.py):

   • Added a new FastAPI router mounted at /version.
   • The /version endpoint returns diagnostics data as JSON, full HTML, or a partial HTML fragment.
   • The partial HTML fragment is rendered using the new template version_info_partial.html.
   • The endpoint requires authentication.
   • The partial response logs "Serving partial version info" (currently a print statement).

2. Frontend (mcpgateway/static/admin.js):

   • Added a new tab "Version and Environment Info" with id "tab-version-info".
   • Added an event listener for clicking this tab that logs "Version and Environment Info tab clicked - triggering showTab" and calls showTab("version-info").
   • The tab panel with id "version-info-panel" loads the partial HTML from /version?partial=true via fetch.

3. Templates:

   • version_info_partial.html: A styled card displaying version and environment info with a "Copy JSON to Clipboard" button.
   • admin.html: Added the new tab "Version and Environment Info" in the navigation and a corresponding hidden div panel for the content.

Love it, having it integrated into the UI as opposed to an external link is great. We should expand the fields with a future PR.

@manavgup I tried adding a gateway from the Gateways/MCP Servers tab, but could not. Looks like the "Add Gateway" functionality is broken from the UI. Did not see any calls going to the MCP server.
