added comment section on card details to avoid loading the card comment activities from the server

- and added to show only the activities a card

- to display the card comments a connection to the server was needed to get the activities of the card comments, now, it's not necessary
- also performance relevant. until now there were a lot of activities loaded, now only of the current card
