API to list and manage assigned requests as an HL participant about quarantine-help-api

You should be able to copy most stuff from the /api/v1/me/requests endpoint implementation.

Great stuff. One more thing we need to think about:

1. When an assignee finished up a request, we might want to change the related RequestAssignment object status from Assigned to Completed.
2. When an assignee drops a request midway after assigning, we might want to change the related RequestAssignment object status from Assigned to Dropped.

Also, we might want to have a way for an Assignee to drop a request after assigning it (case 2).

I think (1) and (2) above was done in a previous commit. Closing this as resolved. Thank you @igarcez. ✅ We lack tests, and I blame me.
