NoJavaScript support feedback for first load

[LeeNX]

Describe the Web Server enhancement

Please can we add the NoJavaScript warning to the first page load of ESPHome.

Use cases

Ran into an issue, where my FireFox running NoJavaScript plug stop ESPHome from loading and I did waste a bunch of time trying to debug ESPHome, where there was nothing wrong, but the above warning would have been super useful.

Visual examples (optional)

No response

I did think maybe some screenshots might help.

The first been a blank screen, but that would be after login, this was troubling.

But possible adding a warning to the login screen would help too.
