Remove fetch request from heatmap (#13623)

* Remove fetch request from heatmap

Render heatmap data directly to HTML, eliminating one HTTP request on
frontpage and user profile. Also added min-height to the container so
the page content will no longer move after loading.

* rename and error display

* also log the js error

* add error handler

* remove useless inline style and hide divider on small screens

* Update routers/user/home.go

* Update routers/user/profile.go
