Tell customers when they hit the widget limit

[nbolton]

Feature request.

I discovered that when adding 13 text labels, the 13th does not render and no error is displayed.

Workaround: Delete a label that you don't need, then delete and re-create the 13th text label to get it to render.

Edit: @eepetrash suggested that I may have hit the widget limit for my pricing tier: https://github.com/blynkkk/blynk_Issues/issues/223#issuecomment-1270177319

It would be helpful if Blynk tells customers when they hit the widget limit, which would prompt them to upgrade (instead of staying silent).

@doom369 also seems to happen for labelled values too.

Still experiencing this issue.

@nbolton this sounds like hitting a widget limit: https://blynk.io/pricing

I see! Ok, thanks.
