* fix(s3api): route STS GetFederationToken requests to STS handler (#9157)

The STS GetFederationToken handler was implemented but never reachable.
Three routing gaps sent requests to the S3/IAM path instead of STS:

- No explicit mux route for Action=GetFederationToken in the URL query
- iamMatcher did not exclude GetFederationToken, so authenticated POSTs
  with Action in the form body were matched and dispatched to IAM
- UnifiedPostHandler only dispatched AssumeRole* and GetCallerIdentity
  to STS, leaving GetFederationToken to fall through to DoActions and
  return NotImplemented

Add the missing route, the matcher exclusion, and the dispatch branch.

Also wire TestSTS, TestAssumeRoleWithWebIdentity, and TestServiceAccount
into the s3-iam-tests workflow as a new "sts" matrix entry. Before this
change, none of test/s3/iam/s3_sts_get_federation_token_test.go's four
test functions ran in CI, which is why this regression shipped.

* test(iam): make orphaned STS/service-account tests pass under auth-enabled CI

Follow-up to wiring STS tests into CI: fixes several pre-existing issues
that made the newly-included tests fail locally.

Server fixes:
- weed/s3api/s3api_sts.go: handleGetFederationToken no longer 500s when
  the caller is a legacy S3-config identity (not in the IAM user store).
  Previously any GetPoliciesForUser error short-circuited to InternalError,
  which hard-failed every SigV4 caller using keys from -s3.config.
- weed/s3api/s3api_embedded_iam.go: CreateServiceAccount now generates IDs
  in the sa:<parent>:<uuid> format required by
  credential.ValidateServiceAccountId. The old "sa-XXXXXXXX" format failed
  the persistence-layer regex and caused every CreateServiceAccount call
  to return 500 once a filer-backed credential store validated the ID.

Test helpers:
- test/s3/iam/s3_sts_assume_role_test.go: callSTSAPIWithSigV4 no longer
  sets req.Header["Host"]. aws-sdk-go v1 v4.Signer already signs Host from
  req.URL.Host, and a manual Host header made the signer emit host;host in
  SignedHeaders, producing SignatureDoesNotMatch. Updated missing_role_arn
  subtest to match the existing SeaweedFS behavior (user-context
  assumption).
- test/s3/iam/s3_service_account_test.go: callIAMAPI now SigV4-signs
  requests when STS_TEST_{ACCESS,SECRET}_KEY env vars are set. Unsigned
  IAM writes otherwise fall through to the STS fallback and return
  InvalidAction.

CI matrix:
- .github/workflows/s3-iam-tests.yml: skip
  TestServiceAccountLifecycle/use_service_account_credentials only. The
  rest of the service-account suite passes; that one subtest depends on a
  separate credential-reload issue where new ABIA keys briefly register
  into accessKeyIdent but aren't persisted to the filer, so they vanish
  on the next reload. Out of scope for the #9157 GetFederationToken fix.

* fix(credential): accept AWS IAM username chars in service-account IDs

Gemini review on #9167 pointed out that ServiceAccountIdPattern's
parent-user segment was more restrictive than an AWS IAM username:
`[A-Za-z0-9_-]` vs. IAM's `[\w+=,.@-]`. Realistic usernames with
`@`, `.`, `+`, `=`, or `,` (e.g. email-style principals) would fail
validation at the filer store even though the embedded IAM API
happily created them.

Broaden the regex to `[A-Za-z0-9_+=,.@-]` (matching the AWS IAM spec
at https://docs.aws.amazon.com/IAM/latest/APIReference/API_User.html)
and add a table-driven test that locks the expansion in.

* address PR review feedback on #9167

All five review items were valid; changes keyed to review bullets:

- weed/s3api/s3api_sts.go: handleGetFederationToken no longer swallows
  arbitrary policy-lookup failures. Only credential.ErrUserNotFound is
  treated leniently (the legacy-config SigV4 path); any other error now
  returns InternalError so we don't mint tokens with an incomplete
  policy set.
- weed/credential/grpc/grpc_identity.go: GetUser translates gRPC
  NotFound back to credential.ErrUserNotFound so errors.Is(...) above
  matches for gRPC-backed stores, not just memory/filer-direct.
- weed/s3api/s3api_embedded_iam.go: CreateServiceAccount now validates
  the generated saId against credential.ValidateServiceAccountId before
  returning. Surfaces a client 400 with the offending ID instead of the
  opaque 500 that used to bubble up from the persistence layer.
- weed/s3api/s3api_server_routing_test.go: seed a routing-test identity
  with a known AK/SK, sign TestRouting_GetFederationTokenAuthenticatedBody
  with aws-sdk-go v4.Signer so the request actually passes
  AuthSignatureOnly. Assert 503 ServiceUnavailable (from STSHandlers
  with no stsService) instead of just NotEqual(501) — 503 proves the
  dispatch reached STSHandlers.HandleSTSRequest.
- test/s3/iam/s3_service_account_test.go: callIAMAPI signs with
  service="iam" instead of "s3" (SeaweedFS verifies against whichever
  service the client signed with, but "iam" is semantically correct).
- weed/credential/validation_test.go: add positive rows for an
  uppercase parent (sa:ALICE:...) and a canonical hyphenated UUID
  suffix (sa:alice:123e4567-e89b-12d3-a456-426614174000).

Refine error handling to provide clearer messages when checking for
existing service accounts.

* [PostgresStore] add nil guards and validation to service account methods

Ensure input parameters are not nil and required IDs are present
to prevent runtime panics and ensure data integrity.

* [JS] add shared IAM utility script

Consolidate common IAM operations like deleteUser and deleteAccessKey
into a shared utility script for better maintainability.

Added Errorf log if AtomicRenameEntry fails during migration to ensure visibility of common failure points.

* credential: allow uppercase characters in service account ID username

or a numeric page argument. This prevents errors when goToPage(1)
