Bulk file uploads (Excel)

Two bulk flows share the same pipeline—see the Bulk upload guide.

1. Funding source links (contacts): GET /v1/funding-source-link/template → fill XLSX → GET + PUT S3 → POST /v1/storage/upload/bulk-contact (keyType: BULK_CONTACT) → POST /v1/funding-source-link/bulkAdd
2. Direct funding sources: GET /v1/funding-source/template → fill XLSX → GET + PUT S3 → POST /v1/storage/upload/funding-source (keyType: BULK_FUNDING_SOURCE) → POST /v1/funding-source/bulkAdd

Template APIs return entity.fileUrl (HTTPS download link). Register-upload expects the full S3 URL from the pre-signed upload; bulkAdd expects the relative entity.fileUrl from register-upload.

PUT the XLSX to the pre-signed URL without Swirepay authorization headers.
