Make titles in the UI consistent

[marko-lisica]

Problem

Currently in the UI, we don't have rules on what title sizes we use in different areas of the product (sections, sub-sections, dashboard cards, empty states, error states, etc.)

Context

More context in this story's comments.

Possible solution

Define title sizes that should be used in the product and specify where should each size be used.
