Initial specification

When a valuator is selected to comment on a proposal in the backend system, the valuator receives an email notification including a link to the proposal in the backend system.

Context:

To assign a valuator, first this user needs to be added into the process as a "process/assembly admin" with the role of "valuator".
Once this is done, valuators can be assigned to individual proposals. This is done by check the checkbox in the list of proposals (admin):

(choose "assign to valuator")

(press "assign")

Currently, this assigns the "valuator" capability to the assigned user, however this does not generate any notification/email to the user.

Task:

• Identify the command that assigns a valuator to the selected proposals
• Create a new mailer job that sends an email to this evaluator with a link to each of the proposals assigned in the admin.
• Add tests for the task

Email text:

Thanks for your help!
