* feat: Implement IAM managed policy operations (GetPolicy, ListPolicies, DeletePolicy, AttachUserPolicy, DetachUserPolicy)
- Add response type aliases in iamapi_response.go for managed policy operations
- Implement 6 handler methods in iamapi_management_handlers.go:
- GetPolicy: Lookup managed policy by ARN
- DeletePolicy: Remove managed policy
- ListPolicies: List all managed policies
- AttachUserPolicy: Attach managed policy to user, aggregating inline + managed actions
- DetachUserPolicy: Detach managed policy from user
- ListAttachedUserPolicies: List user's attached managed policies
- Add computeAllActionsForUser() to aggregate actions from both inline and managed policies
- Wire 6 new DoActions switch cases for policy operations
- Add comprehensive tests for all new handlers
- Fixes#8506

* fix: address PR review feedback for IAM managed policy operations
- Add parsePolicyArn() helper with proper ARN prefix validation, replacing
fragile strings.Split parsing in GetPolicy, DeletePolicy, AttachUserPolicy,
and DetachUserPolicy
- DeletePolicy now detaches the policy from all users and recomputes their
aggregated actions, preventing stale permissions after deletion
- Set changed=true for DeletePolicy DoActions case so identity updates persist
- Make PolicyId consistent: CreatePolicy now uses Hash(&policyName) matching
GetPolicy and ListPolicies
- Remove redundant nil map checks (Go handles nil map lookups safely)
- DRY up action deduplication in computeAllActionsForUser with addUniqueActions
closure
- Add tests for invalid/empty ARN rejection and DeletePolicy identity cleanup

* feat: add integration tests for managed policy lifecycle (#8506)
Add two integration tests covering the user-reported use case where
managed policy operations returned 500 errors:
- TestS3IAMManagedPolicyLifecycle: end-to-end workflow matching the
issue report — CreatePolicy, ListPolicies, GetPolicy, AttachUserPolicy,
ListAttachedUserPolicies, idempotent re-attach, DeletePolicy while
attached (expects DeleteConflict), DetachUserPolicy, DeletePolicy,
and verification that deleted policy is gone
- TestS3IAMManagedPolicyErrorCases: covers error paths — nonexistent
policy/user for GetPolicy, DeletePolicy, AttachUserPolicy,
DetachUserPolicy, and ListAttachedUserPolicies
Also fixes DeletePolicy to reject deletion when policy is still attached
to a user (AWS-compatible DeleteConflictException), and adds the 409
status code mapping for DeleteConflictException in the error response
handler.

* fix: nil map panic in CreatePolicy, add PolicyId test assertions
- Initialize policies.Policies map in CreatePolicy if nil (prevents panic
when no policies exist yet); also handle filer_pb.ErrNotFound like other
callers
- Add PolicyId assertions in TestGetPolicy and TestListPolicies to lock in
the consistent Hash(&policyName) behavior
- Remove redundant time.Sleep calls from new integration tests (startMiniCluster
already blocks on waitForS3Ready)

* fix: PutUserPolicy and DeleteUserPolicy now preserve managed policy actions
PutUserPolicy and DeleteUserPolicy were calling computeAggregatedActionsForUser
(inline-only), overwriting ident.Actions and dropping managed policy actions.
Both now call computeAllActionsForUser which unions inline + managed actions.
Add TestManagedPolicyActionsPreservedAcrossInlineMutations regression test:
attaches a managed policy, adds an inline policy (verifies both actions present),
deletes the inline policy, then asserts managed policy actions still persist.

* fix: PutUserPolicy verifies user exists before persisting inline policy
Previously the inline policy was written to storage before checking if the
target user exists in s3cfg.Identities, leaving orphaned policy data when
the user was absent. Now validates the user first, returning
NoSuchEntityException immediately if not found.

* fix: prevent stale/lost actions on computeAllActionsForUser failure
- PutUserPolicy: on recomputation failure, preserve existing ident.Actions
instead of falling back to only the current inline policy's actions
- DeleteUserPolicy: on recomputation failure, preserve existing ident.Actions
instead of assigning nil (which wiped all permissions)
- AttachUserPolicy: roll back ident.PolicyNames and return error if
action recomputation fails, keeping identity consistent
- DetachUserPolicy: roll back ident.PolicyNames and return error if
GetPolicies or action recomputation fails
- Add doc comment on newTestIamApiServer noting it only sets s3ApiConfig
