Previously, we didn't differentiate between model install errors for different types of model install sources, resulting in a buggy UX:
- If a HF model install failed, but it was a HF URL install and not a repo id install, the link to the HF model page was incorrect.
- If a non-HF URL install (e.g. civitai) failed, we treated it as a HF URL install. In this case, if the user's HF token was invalid or unset, we directed the user to set it. If the HF token was valid, we displayed an empty red toast. If it's not a HF URL install, then of course neither of these are correct.
Also, the logic for handling the toasts was a bit complicated.
This change does a few things:
- Consolidate the model install error toasts into one place - the socket.io event handler for the model install error event. There is no more global state for the toasts and there are no hooks managing them.
- Handling the different cases for errors, including all combinations of HF/non-HF and unauthorized/forbidden/unknown.
- Ensure the currently-rasterizing adapter is reset to `null` on success or failure of a rasterization operation. In case of failure, this prevents the UI from getting stuck with a disabled Invoke button and tooltip message "Canvas is busy (rasterizing)".
- Log the error if there is one.
The "adding to" text indicates if images are going to the gallery or staging area. This info is relevant only to the canvas tab, but was displayed on Upscaling and Workflows tabs. Removed it from those tabs.
A redux selector is used to get the "default" IP Adapter. The selector uses the model list query result to select an IP Adapter model to be preset by default.
The selector is memoized, so if we mutate the returned default IP Adapter state, it mutates the result of the selector for all consumers.
For example, the `image` property of the default IP Adapter selector result is `null`. When we set the `image` property of the selector result while creating an IP Adapter, this does not trigger the selector to recompute its result. We end up setting the image for the selector result directly, and all other consumers now have that same image set.
Solution - we need to clone the selector result everywhere it is used. This was missed in a few spots, causing the issue.
It was easy to misunderstand the empty state for a regional guidance reference image. There was no label, so it seemed like it was the whole region that was empty.
This small change adds the "Reference Image" heading to the empty state, so it's clear that the empty state messaging refers to this reference image, not the whole regional guidance layer.
