Removed delete and edit icons from card and added functionality to show owner of shared card

[MiliMade]

Description

This code adds a function that searches the firestore database for user details using a users id. The id for each card is taken from the path string. If the user id does not match the current user id (id of the user signed in) then the card show's the name of the owner of the list.
Both the delete and edit icons were also removed.
