💄 [#2194] Correct use of Sections and other gaps

[jiromaykin]

This PR solves wrong section styles and some other faulty gaps/margins/paddings here and there.
issue: https://taiga.maykinmedia.nl/project/open-inwoner/issue/2194

the main issue is a bit of a 'blame' because some styles were put inside 'contactmomenten' that did not belong there + all Section tags in the entire project were styled wrong because of the CSS that was targeting all Section Tags instead of a .[componentname]-section class (we need to target components instead of everything everywhere all at once 🙂)

inside scope of this issue:

• remove margins from section tags, check to see if section styling doesn't break everywhere

outside scope of this issue so did is as an extra

• delete pagination styling from wrong file - move to .pagination component and remove table display
• improve card spacing for Userfeed and other Cards
• remove unnecessary margin on Mijn Aanvragen page

[jiromaykin]

Removing this code presented the original issue of wrongly styled sections.
