[CardSearch] Add card completion popups to chats and search fields (#7089)

Browse source 
* Add card completion popups to chats and search fields

Completes @mention and [[card]] in chat, and card names in the deck
editor, EDHREC, Archidekt, card art rules, and user card settings
searches. Pops up a styled list with mana pips and a card image
preview, flipping the list order when the popup opens above the text
field.
