Since we're nesting these fields under the client object, I think it might make more sense to avoid repeating the client_ suffix for the field names — WDYT?

{
  "client": {
    "id": "...",
    "name": "...",
    "uri": "...",
  }
}

If the client_id is the id column in the table, I think it shouldn't result in any confusion.

🤦 vibe coded this "small" change, sorry. fixed it now!

p.s I updated this, but it also impacts the existing endpoint (GET /oauth/authorizations/{authorization_id}) response, I'll add this to release notes as it'll break the existing beta users'.
