Contract 9.1.1

The war trophies note names the field each response serves: war_history over seasons carries our_clan_war_trophies, and the note named clan_war_trophies there. It no longer names another tool's field either (the acceptance suite's notes check, on the 9.1.0 deploy).

/oauth/userinfo answers a person's grant for the JSON API (/api/v1) as it does one for /mcp, so a family app that signs in for the JSON API learns the account id and address; an agent's grant is still refused.
