Integration of a functionality to enable forwarding of reports from the secondary tenant to root tenant

[evilaliv3]

Proposal

Following the development of feature #4330 this ticket is to implement similar functionality in the opposite direction (input).

The idea behind this functionality is to make it possible for an external organization already accrediotated to the system to insert into the system visible both on the secondary and root tenant.

This implementation is intended to be used to enable the organization to forward a report they had received and intended to be accessed by the recipient of the root tenant.

Following the implementation:

• a user (recipient) of the secondary tenant should be able to insert a report into the system desalinating it to recipients
• the recipient of the secondary tenant should receive a temporary receipt to be provided to whistleblowers; Whistleblowers accessing with this receipt should be able to see the loaded information and exchange messages with the recipients of the root tenant.
• the recipient of the secondary tenant by accessing should be able to eventually exchange comments with the recipients of the root tenant but should not be able to see the comments exchanged between the whistleblower and the recipients of the root tenant.
