🛠️ To fix

Product designer: @marko-lisica
Truncate the label name to make sure that the width of the Activity and Labels card is 50% of the viewport width. E.g. if the label name is too long, then we make the Activity card narrow to fit the label name.

If the label is truncated, show a tooltip with the whole name on hover.
