Chris Lu 08bd1e2563 s3tables: Pre-validate namespace to return 400 instead of 500 ...

Move validateNamespace call outside of filerClient.WithFilerClient closure
so that validation errors return HTTP 400 (InvalidRequest) instead of 500
(InternalError).

Before: Validation error inside closure → treated as internal error → 500
After: Validation error before closure → handled as bad request → 400

This provides correct error semantics: namespace validation is an input
validation issue, not a server error.
