[Enhancement] Cards | add delete button to each row

[iKrushYou]

I figured out that you can delete a card by removing the name and the card number. This is not very intuitive and it would be much more convenient if there was a button to delete a user (with a confirmation alert especially).

This is a deliberate design choice - there is almost never a need to delete a card. The UI makes the most common operations straightforward:

• somebody who loses their access card gets assigned a new card with the same permissions
• somebody who is leaving returns back their access card and they are removed from the system but the card stays on the system to be assigned to an incoming person or replacement

However, all the code is available and MIT licensed so you are free to modify it as you see fit.
