Redeem Points UI

[Brojowski]

the routes:

khe.io/redeem

• this should be a UI that takes a 5 digit code(ex: ABCDE) then redirects to it (khe.io/ABCDE)
• the server will redirect to a /redeem/pointId url

khe.io/redeem/pointId

• this should redeem points using the frontend-lib
• display error messages or show points were awarded
