Scopes: Fix zod schema for scope spec

[mdvictor]

What is this feature?

Builds on top of this PR. I realized now that the recent scopes no longer show up due to the zod schema being too strict. I am not sure about the contract here, but IIRC the title and description are the only required properties? All the other are optional? Please correct me if I'm wrong.

In any case, this change brings back the recent scopes in the selector as parseScopesFromLocalStorage returns the proper objects from local storage.

Why do we need this feature?

Show recent scopes again.

Who is this feature for?
