Authorization + signatureFirm bankingSchema in review

Creates one asynchronously processed collection. Detailed fields will be confirmed with the sandbox release.

The detailed schema is still being confirmed. After sign-in, Try still sends the form body to the sandbox.

This API needs a Signature header. The portal signs when that company code has a signing key configured. Without it, the sandbox receives the request unsigned.
