Uniformize all timelines padding and width

[Granja5]

Closes #1492

I think it is done, given the differences in how the pages were constructed the exact values of paddings and sizes are different, but visually I think they are almost indistinguishable now.

In another note, shouldn't the restaurant page's week be starting from Sunday?
