Resolving a typical Console GraphQL query triggers many parallel
authorize calls (one per resource per field resolver). This commit
collapses them via a dataloader: parallel calls within the same
request are gathered into a single iam.Authorizer.AuthorizeMulti pass,
and only fall back to per-item Authorize when AuthorizeMulti rejects
the whole batch (e.g. mixed organizations).
The loader key encodes resource id, action, options, and a canonical
JSON-encoded attribute map so logically identical calls share a key
while differing ones do not. The loader is created without caching so
repeated calls within a request still produce one audit log entry per
call. dataloader.NewAuthorizeFunc preserves the existing
authz.AuthorizeFunc signature and error mapping.
