Merge branch 'main' into reatang/iam-issue-analysis-d4fb97

The v4 runtime capabilities response carried no admin.iam.* entries, so
the rc client's capability gate rejected policy detach even though the
detach route is implemented (rustfs/backlog#1900). Advertise the IAM
admin capability set as a flat named list whose statuses are derived
from the public admin route inventory, so the advertisement tracks the
actually registered routes instead of a hardcoded claim.
