User model and namespace in policy stub is hardcoded for query functions
In `policy.stub` in the lower functions, the dockblock comment uses a hardcoded (and incorrect) namespace
```
@param \App\Model\User $user
```
instead of
```
@param \{{ namespacedUserModel }} $user
```
This occurs for:
- `qualifyCollectionQueryWithUser()`
- `qualifyItemQueryWithUser()`
- `qualifyStoreDataWithUser()`
- `qualifyUpdateDataWithUser()`
