Design review issues

[juliusknorr]

This is a collection of design fixes that need to be done for the updated design in Hub 9 / Nextcloud 30.

• Verify that we migrate hardcoded 44px values to the relevant css variables
• Deck: Inputline half white half blue
  
• Adjust header styles
  • Deck: Text size for Todo, Doing and Done too big compared with the rest of the UI
    
  • Deck: ‘Deleted items’ is cut and not readable. Text of ‘Deleted lists’ and ‘Deleted card’ is too big.
    
• Deck: Card Details dialog has scrollbars.
  
• Deck: ‘...’ and + buttons are not aligned
