fix: close modal after deleting card

[ludij]

• Resolves: # 6263 -> delete card in modal view: modal should close #6263
• Target version: main

Summary

When a card is opened in the modal or sidebar and then deleted, the router now goes to the board, so that the modal closes. The sidebar was already closing, but incorrectly kept the URL for the card.
