Add edit score feature to host settings panel

[jacten]

Occasionally the score can get messed up by someone clicking the wrong buttons following a turn. The goal of this is to add fields to adjust the score for each team.

Should coordinate with @anderspollack on designs, but open to creating your own designs and taking feedback.

Requirements

• Edit restAPI documentation with new endpoint for editing score
• Add to client
• Add testing
• Add route, controller
