Creates a badge.
The createBadge() function returns a Promise that resolves to the newly created badge.
New badges do not have any badge permissions by default. You can set badge permissions from the Badges page in the Dashboard.
If backgroundColor or textColor are not specified, they default to "#796EFF" (purple) and "#FFFFFF" (white) respectively.
This function requires elevated permissions and runs only on the backend and on dashboard pages.
