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.
- Update canvas slice's to track the current base model architecture instead of just the optimal dimension. This lets us derive both optimal dimension _and_ grid size for the currently selected model.
- Update all bbox size utilities to use derived grid size instead of hardcoded values of 8 or 64
- Review every damned instance of the number 8 in the whole frontend and update the ones that need to use the grid size
- Update the invoke button blocking logic to check against scaled bbox size, unless scaling is disabled.
- Update the invoke button blocking to say if it's width or height that is invalid and if its bbox or scaled, for both FLUX and the T2I adapter constraints
This hook forcibly updates _all_ portals with `data-hidden=true` when the modal opens - then reverts it when the modal closes. It's intended to help screen readers. Unfortunately, this absolutely tanks performance because we have many portals. React needs to do alot of layout calculations (not re-renders).
IMO this behaviour is a bug in chakra. The modals which generated the portals are hidden by default, so this data attr should really be set by default. Dunno why it isn't.
