Host side validation for player submitted cards

There is currently no validation that the player submitted all of their cards, this is trusting the client. We should verify the player has submitted the correct amount of cards on the host side of the application. This also means that we should reset the player's state to ensure they have the exact data they need to send the proper amount of cards.

• Reset the cards in the player's hand + number of cards needed for selection based on the host context.
