fix(iam): PathPrefix + pagination in ListAttached*Policies#1999
Merged
Conversation
…up}Policies These three ops hardcoded IsTruncated=false and ignored PathPrefix, Marker, and MaxItems, so boto3 paginators and terraform treated page 1 as the complete set and PathPrefix queries returned unfiltered data. Add a shared paginate_attached_policies helper (filter by the policy ARN's embedded path, marker-cursor by ARN, MaxItems-bounded) and render IsTruncated + Marker from it. Test: attach two policies on different paths to a role; PathPrefix selects only the matching one; MaxItems=1 truncates with a marker and the second page returns the rest, each attachment appearing exactly once.

Summary by cubic
Fixes IAM ListAttachedRolePolicies/UserPolicies/GroupPolicies to honor PathPrefix and real pagination (Marker/MaxItems). Restores correct filtering and makes boto3 and Terraform paginators behave correctly.
