- Each entity gets its own `CanvasEntityFilterer`
- Add auto-preview feature to filter, debounced by 1000ms leading + trailing
- Fix flash when preview updates

Hopefully this resolves the issue w/ alt as a quick switch for color picker on windows.

- Add selectors to get the default control adapter and ip adapter with model, preferring controlnet over t2i adapter for model
- Add hooks to add each entity type, using the defaults
- Add hooks to add prompts/ip adapters to a regional guidance layer
- Use the defaults in other places where we add control layers or ip adapters (e.g. dnd-triggered entity creation)

This API is not available in all browsers. Also add an eslint rule to prevent usage in the future.

There's a race condition where we sometimes get progress events from canceled queue items, depending on the timing of the cancellation request and last event or two from the queue item.

I can't imagine how to resolve this except by tracking all cancellations and ignoring events for cancelled items, which is implemented in this change.
