Add entire in Admin for managing HelpLink
Add entire in Admin for managing HelpLink

An admin can _only_ modify the hyperlink associated with a HelpLink.

As a consequence, you cannot add new instances of the model nor delete
them. Only the existing HelpLinks can be modified because their
inclusion (or existence) is dependent upon the usage within the UI.

If one *must* do something to add or delete or override what is allowed
via Django Admin, they will _need_ database/SQL level access given this
current implementation.

See ATMO-1230 & ATMO-1270 for more context.
