fix: follow redirects when fetching uploaded files for MIME type detection

[paulpopus]

Summary

• When using S3 (or any storage adapter) with signedDownloads enabled, the staticHandler returns a 302 redirect to a pre-signed URL. Payload's addDataAndFileToRequest utility calls this handler internally to fetch back the just-uploaded file for MIME type detection, but Node.js fetch does not automatically follow redirects on a Response object returned from an internal handler call — resulting in an empty ArrayBuffer and a DataView.getUint16() bounds error.
• The existing guard in the S3 staticHandler (if (signedDownloads && !clientUploadContext)) was meant to skip the redirect for internal upload processing, but fires anyway when clientUploadContext is undefined (i.e. when no upload context is configured for the collection).
• Added redirect-following between receiving the handler response and consuming its body: if the response is a 3xx redirect, addDataAndFileToRequest now follows the Location header to retrieve the actual file bytes before processing.
