Loading default workflows sometimes requires we mutate the workflow object in order to change the category or ID of the workflow.
This happens in `invokeai/frontend/web/src/features/nodes/util/workflow/validateWorkflow.ts`
The data we get back from the query hooks is frozen and sealed by redux, because they are part of redux state. We need to clone the workflow before operating on it.
It's not clear how this ever worked in the past, because redux state has always been frozen and sealed.
With the change to model identifiers from v3 to v4, if a user had persisted redux state with the old format, we could get unexpected runtime errors when rehydrating state if we try to access model attributes that no longer exist.
For example, the CLIP Skip component does this:
```ts
CLIP_SKIP_MAP[model.base].maxClip
```
In v3, models had a `base_type` attribute, but it is renamed to `base` in v4. This code therefore causes a runtime error:
- `model.base` is `undefined`
- `CLIP_SKIP_MAP[undefined]` is also undefined
- `undefined.maxClip` is a runtime error!
Resolved by adding a migration for the redux slices that have model identifiers. The migration simply resets the slice or the part of the slice that is affected, when it's simple to do a partial reset.
Closes#6000
- Display a toast on UI launch if the HF token is invalid
- Show form in MM if token is invalid or unable to be verified, let user set the token via this form
When consolidating all the model queries I messed up the query tags. Fixed now, so that when a model is installed, removed, or changed, the list refreshes.
In order to allow for null and undefined metadata values, this hook returned a symbol to indicate that parsing failed or was pending.
For values where the parsed value will never be null or undefined, it is useful get the value or null (instead of a symbol).
