Added support for http forgejo hosts

Fixed display of one more column than expected in widgets on certain weekdays. I messed up the calculation of the offset while adding the smaller widget size.

Fixes messed up widget from 1.1 (one column was missing in both sizes) Depending on your screen size the trailing padding my be less that leading.  I know about the issue, but not yet how to fix it in a satisfying way, as widgets are very constraining the layout and I want to keep the squares for days.

A “small” option was added for the heatmap widget (2x2 tiles)
