* s3tables: report a delete the filer rejected

deleteDirectory discarded DeleteEntryResponse and checked only the
transport error, so DeleteTable, DeleteNamespace, DeleteView and
DeleteTableBucket answered 200 for a delete the filer refused. Call
filer_pb.DoRemove, which reads resp.Error and still treats a missing
entry as success.

* admin: report a delete the filer rejected

The bucket delete, the file browser handlers and the topic retention
purger all discarded DeleteEntryResponse, so a delete the filer refused
came back as success. Call filer_pb.DoRemove, which reads resp.Error.

* credential: report a delete the filer rejected

DeleteUser, DeletePolicy and the full-sync cleanup loops discarded
DeleteEntryResponse, so a rejected delete answered success and left the
credential file in place. The service account path in the same store
already read resp.Error; the rest now do too, via filer_pb.DoRemove
where not-found is already tolerated.

* shell: report a delete the filer rejected

remote.configure -delete, remote.cache and the remote metadata sync
discarded DeleteEntryResponse, so a rejected delete printed as removed.
Call filer_pb.DoRemove, which reads resp.Error.

* mq: report a delete the filer rejected

The consumer offset group purge and the coordinator assignment delete
discarded DeleteEntryResponse. Call filer_pb.DoRemove, which reads
resp.Error.

* iam: count only the revocation entries the filer actually deleted

The expiry sweep discarded DeleteEntryResponse, so a rejected delete was
counted as purged and the entry stayed. Call filer_pb.DoRemove, which
reads resp.Error, matching the role and provider stores beside it.

* mount: fail rmdir when the unary fallback delete was rejected

The streaming branch turns DeleteEntryResponse.Error into an error, the
unary fallback dropped it, so rmdir of a non-empty directory answered OK
off the stream and ENOTEMPTY on it. Surface it in both.

* s3tables: fail DeleteTableBucket when the directory delete is refused

The handler only failed when both the leaf entry and the directory
delete failed, so a refused bucket directory delete still answered 200
with the bucket in place. The directory is the bucket, so it decides;
the leaf entry stays best-effort.

Chris Lu 9d6a699b94 feat(iam): opt-in session revocation via JTI blocklist (Phase 3d) (#9324)
* feat(iam): claim-based policy mode for AssumeRoleWithWebIdentity

When the caller passes the sentinel RoleArn arn:aws:iam:::role/sts-claim-based
(or omits it entirely) and the matched OIDC provider has policyClaim set,
mint a session whose effective policies come from that JWT claim instead
of from a server-side role mapping. Accepts string, comma-separated
string, or array shapes — MinIO-compatible behaviour for IDPs that
already attach policies to the user.

Trust-policy validation is skipped in claim-mode: the IDP is the sole
authority for both authentication and authorization, mirroring the
contract MinIO documents for its DummyRoleARN flow. Concrete-role mode
is unchanged and still requires the role definition + trust policy.

* fix(iam): trim policy-claim array elements + clean up stale comments

Three medium-priority cleanups gemini flagged on the claim-based path:

- extractClaimPolicies's array branch was leaving whitespace on each
  element while the string/comma-separated branch trimmed via
  splitPolicyClaimString. An IDP that emits ["readonly", " billing "]
  would create a "billing" policy lookup that didn't match the stored
  name. Trim every array element, drop empties.
- The "synthetic ARN keyed on the session name" comment was wrong —
  effectiveRoleArn here is the literal sentinel; it's the assumed-role
  ARN generated downstream that's session-keyed. Reword.
- The empty if/else block at the start of
  validateAssumeRoleWithWebIdentityRequest existed only to host a
  comment about deferred validation; the comment now lives in the
  function godoc and the empty branch is gone.

Addresses three gemini medium reviews on PR #9322.

* feat(iam): account-scoped OIDC providers

Add OIDCProviderRecord.AccountID enforcement: when a role lives in
account A, the OIDC provider validating the assume-role token must be
either global (AccountID="") or also live in account A. Cross-account
use is rejected at the IAM-manager layer before reaching the trust
policy validator.

OIDCProviderStore gains GetProviderByIssuerAndAccount; both the in-
memory and filer-backed stores implement it. Static-config-only
deployments are unaffected since they don't populate the store.

* fix(iam): account-scoped lookup for cross-account check

enforceProviderAccountScope was calling GetProviderByIssuer, which
returns the first match arbitrarily when multiple providers share an
issuer (one global + one per tenant is the canonical setup). On a
two-record collision the wrong record could come back first and
falsely reject a valid same-account or global-provider request.

Use GetProviderByIssuerAndAccount as the primary lookup so the
filter happens in the store. On miss, fall back to
GetProviderByIssuer purely to distinguish "issuer entirely unknown"
(let the STS layer reject) from "issuer registered in a different
account" (surface a precise cross-account error).

Addresses gemini high-priority review on PR #9323.

* feat(iam): opt-in session revocation via JTI blocklist

Add SessionRevocationStore (memory + filer implementations) and wire
it into the IAMManager.IsActionAllowed path so a revoked session is
rejected on the next signed request. Session JWTs now embed the
session id as the JTI claim, giving the blocklist a stable key
without requiring a second secret.

Operators who don't configure a store keep the existing fully-stateless
behaviour: every session stays valid until natural expiry. Operators
who do configure one accept one filer lookup per signed request in
exchange for being able to invalidate compromised tokens before
expiry. Revocation entries carry the original session expiry so the
blocklist self-trims via PurgeRevokedSessions.

* fix(iam): hash JTI filenames + paginate Purge with proper EOF handling

Three reviewer-flagged issues on the filer-backed revocation store:

1. Path traversal (security-medium): RevokeSession is exported and takes
   an arbitrary string. Using the JTI verbatim as a filename meant a
   caller could pass "../../etc/passwd" to write outside the basePath.
   SHA-1 hash the JTI to a fixed-width hex name; lookups still find the
   entry because Revoke and IsRevoked share the same hash function.

2. Purge swallowed errors. The inner `err` from stream.Recv() shadowed
   the outer err and the loop just broke on any failure, so a mid-stream
   gRPC error returned (count, nil) and the caller had no idea the
   purge was incomplete. Switch to errors.Is(io.EOF) for end-of-stream
   and propagate everything else.

3. Purge had a hardcoded 10000-entry cap. Stream-paginate via
   StartFromFileName so the operator-cron can clean a backlog larger
   than that without losing rows.
