Recreate cards only on config change

[bramkragten]

Proposed change

We would recreate the entire view on a change of width (like expanding the side menu) and switching edit mode.

We now only recalculate the columns without recreating the cards, for edit mode we wrap the existing cards with card-options instead of recreating the card.

With a lot of cards, and cards that fetch a lot of data on creation like history, this will make a big difference.
