Lookup rep and org info for next steps email

[opticbob]

Background

There are some validation issues with the interplay between the frontend and the backend for the next steps email endpoint. We are going to move from sending a rep name, address, and type to sending a entity_type and entity_id so those values can be looked up on the backend. This will make it easier to cover both selections of individuals and orgs as a whole.

Tasks

• Remove representative_address, _name, and _type fields.
• Add entity_type that should be validated to be individual or organization.
• Add entity_id.
• Use those two new fields to lookup the entities from both the legacy and accredited tables like we do in the PDF data objects.

Acceptance Criteria

• Frontend payloads that match the changes above will send the next steps email from VA Notify and return a 200 status.

I'm working on fixing the last test and the PR for this will be ready for review. I anticipate that happening early tomorrow morning.

I pinged Platform today and was informed that their policy is currently to have developers wait 3 business days after their teammates approval before requesting a PR review.

Platform has commented on the PR but hasn't responded to further comments.
