Create a `POST`, `PATCH`, and `DELETE` endpoint for each admin note entity and establish access layers

[myssto]

Depends on #378

Admin notes need API routes for CRUD actions. They should be routed like:

POST /{entity}/{id}/notes GET /{entity}/{id}/notes PATCH /{entity}/{id}/notes/{noteId} DELETE /{entity}/{id}/notes/{noteId}

Admin notes should be included on the entity's existing DTO for admin users only.

Tasks

Removed OAuthClient from the scope of this issue as it is not particularly relevant right now.
