chore(BA-5829): regenerate api schema dump

The Fragment + AppConfig GraphQL types added in this PR were never
reflected in the committed dump — the live manager schema and the
docs were out of sync. Re-running `dump-gql-schema` +
`generate-supergraph` from this branch lands the new types
(`AppConfigFragment`, `AppConfig`, `myAppConfigs`,
`adminBulkCreate/Update/PurgeAppConfigFragments`, etc.) in the same
PR that introduces them on the Python side.
