Add "teams" functionality and UX

[haypho]

Currently, the "teams" filter is able to be set to 1 or 2. This acts as a multiplier for the number of cards to display. It does not handle any additional logic. It should do the following:

• Continue to support the multiplier logic for the number of cards displayed
• Add separation when generating a "balanced team"
• Add indicators to the card UX to show which team the card is set to
