Final Improvements

[Kristinapn]

• The dropdown for Add Affected Entities should disappear when we click outside of it.
• Profile Picture for the assignments.
• Improve alignment for triangles.
• Sometimes, the selected component version (in the Component Versions view) is not highlighted properly (e.g., the same component version in another folder is not highlighted). Fix that.
• The “show more/show less” button should not only depend on the number of characters in the comment/description, but also on the vertical size of the comment/description (or the number of lines)
