* fix(s3api/iam): fail config snapshot on empty or malformed IAM files A full IAM reload reads every identity/policy/service-account/group file from the filer. When an external secrets tool rewrites a file, a reload that reads it mid-rewrite sees empty or partially-written content. The identity, policy and service-account loaders silently skipped such files (``continue``), so the snapshot was missing entries that still existed on disk. The atomic swap then installed an incomplete identity set while ``isAuthEnabled`` stayed on, denying unrelated clients mid-reload (#11259). The group loader and the read-error paths already fail the snapshot in this situation (a skipped entry reads as deleted). Apply the same behavior to empty content and unmarshal failures across the identity, policy, service-account and group loaders, so a transient mid-rewrite fails the reload (preserving the last known-good state) instead of silently dropping entries. * fix(s3api/iam): coalesce burst IAM config reloads through the reload queue onIamConfigChange did a full synchronous reload for every identity/policy file change event. When several independently-refreshing credentials rewrite their files within the same second, that produced a burst of dozens of back-to-back full reloads, each reading the whole store and widening the window where a mid-rewrite file is observed (#11259). Route every IAM config change through the existing coalescing reload queue (scheduleReload/reloadRetryLoop) instead. A burst of N events now collapses into a single reload (plus one tail reload for events that arrived while one was in flight). scheduleReload gains a reason argument for the existing log line; the reloadRetryLoop already retries failed reloads, so the per-event failure handoff is no longer needed. Tests that asserted on the synchronous reload now wire up the queue (centralized in newTestS3ApiServerWithMemoryIAM) and poll via waitForIdentity/waitForIdentityGone. Adds TestOnIamConfigChangeCoalescesBurstReloads showing 50 events coalesce into <=3 reloads. * fix(s3api/iam): skip non-JSON auxiliary files before failing IAM snapshot Per review: the multi-file loaders unmarshal every entry in an IAM directory, so a non-JSON auxiliary file (README, .DS_Store, a migration backup such as identity.json.old) would hit the new empty/malformed errors and reject the whole snapshot, blocking all later IAM reloads. Only *.json files are IAM objects (SeaweedFS writes identities, policies, service accounts and groups as <name>.json, and other call sites already gate on the .json suffix). Skip non-.json entries at the top of each loader loop, before reading content, so auxiliary files are ignored while empty/malformed .json files still fail the snapshot. Adds TestLoadConfigurationIgnoresNonJsonAuxiliaryFiles. * fix(s3api/iam): reject IAM files with empty identifiers and skip aux in listing Per review: - ListPolicyNames listed every regular entry in the policies directory as a policy name, including non-JSON auxiliary files, but GetPolicy cannot retrieve them. Apply the same .json suffix filter used by the loader so the list only exposes retrievable policies. - json.Unmarshal accepts `{}` and unknown fields. The identity and group loaders merge by the decoded Name (not the file name), so a `{}` file could install an empty-key record and displace a real one; the service-account loader accepted an empty Id. Validate Identity.Name, Group.Name and ServiceAccount.Id (via validateServiceAccountId) after unmarshal and fail the snapshot on empty identifiers. Adds TestFilerEtcStoreListPolicyNamesSkipsNonJsonAuxiliary and empty-identifier regression tests for identity, group and service-account files.
