Provide contact information in the Reject email

When an Access Manager rejects a request, the email should include the Contact details (defined at the namespace) so that the requester could have a way of enquiring about the rejection.

Start by locating the Access Manager rejection email flow and the namespace Contact details definition. Trace how a rejected request is rendered into an email, then verify that the resulting message includes the namespace contact information so the requester can enquire about the rejection.
