auth/grant.go
Create a grant confirmation endpoint and its first test. Lay the framework for how we're going to write endpoints, and how we're going to test them by doing a super simple grant confirmation endpoint (where the user authorizes the grant, which can then be exchanged for a token) and a simple test to ensure that a page gets rendered when valid input is provided. We're still missing a lot of test cases: when different forms of valid input are provided (e.g., no scope, no redirect URI, etc.); when invalid input is provided; etc.
