* fix(s3): accept fresh admin tokens when context carries stale authorization (#12390)
Signed-off-by: Mohd Quamar Tyagi <104281681+Tyagiquamar@users.noreply.github.com>
* security: share the admin Bearer check between S3 and admin-plane peers
Move the authorization scan into security.CheckGrpcAdminToken, built on
IsFilerAdminToken, and call it from CheckGrpcAdminPeer and the S3 IAM cache
check. Both now accept a valid admin token in any authorization value
instead of S3 re-implementing the decode and claim checks.

* filer: accept a fresh admin token after a stale one on IAM gRPC
The S3 IAM cache check is meant to mirror the filer's, so route the filer's
checkAdminAuth through security.CheckGrpcAdminToken too. IamGrpcStore appends
its token to the caller's context, so a forwarded older token would otherwise
still shadow it here.

* security: parse at most four authorization values per admin call
Scanning every value let one request repeat a junk Bearer token (cheap over
HPACK) tens of thousands of times and burn about half a second of JWT parsing
on an unauthenticated port. Real callers send their own token plus at most one
forwarded from their context.

* credential: match the other WithS3InternalAdminAuth replace fix
The plugin worker fix makes the same set-instead-of-append change to
WithS3InternalAdminAuth with different code and a different test at the same
spot, so whichever lands second would conflict. Use the identical code and
test so the two merge cleanly in either order.
