BREAKING Typed NaturalAbstractDetail.data #9819

`NaturalAbstractDetail.data` is implicitly typed with the result of
`service.resolve()`. If needed that type can be widened by specifying
a type for extra properties in the generic, like so:

```ts
class MyComponent extends NaturalAbstractDetail<MyService, {myProp: string}> {
}
```

`getConsolidatedForClient()` was dropped entirely without a replacement.
 It should never be used in our projects (and it was not).

`getDefaultForClient()` was renamed into `getFormExtraFieldDefaultValues()`
to better reflect its usage. It should never be called in projects, only
within Natural itself. Projects were updated to instead call
`getDefaultForServer()`.

The overall behavior of both `NaturalAbstractModelService` and
`NaturalAbstractDetail` is intact.
