v3 fixes and feature requests

[kevireilly]

With the latest version of ESPHome, the v3 devices page can be used via config:

web_server:
  version: 3 

If you do not have the latest version of ESPHome installed, the v3 devices page can be used by specifying the v3 JS specifically:

web_server:
  port: 80
  js_url: https://oi.esphome.io/v3/www.js

If log is turned off, then the data column is pressed to the left edge and takes up no more than 3 screens with FullHD resolution.
If you change the maximum possible width to 1920, it becomes much better.
